Sunday 19 th March. Leader Les Hughes.<br />

Dudmaston.<br />

Our spring foray to Dudmaston was quietly<br />

successful, netting us over forty species.<br />

Sarcoscypha austriaca (Scarlet Elf Cup) was a nice<br />

find. These spectacular<br />

cups grow on mossy<br />

logs in late<br />

winter/early spring and<br />

are always a source of<br />

wonder to me. I<br />

worked as a Colour<br />

Chemist in the printing<br />

ink trade and the<br />

colour of this fungus<br />

rivals any of the<br />

modern pigments. This<br />

was found in the<br />

Dingle and close by,<br />

rust Puccinia buxi and<br />

I think that this is a<br />

first for <strong>Shropshire</strong>.<br />

Another fungus that was found and that I always<br />

associate with this time of year is Polyporus<br />

brumalis. It can be found at almost any time of the<br />

year but it is most common in winter/spring. The<br />

name brumalis means pertaining to winter. Another<br />

find was Ischnoderma benzoinum, an unusual<br />

bracket with only 7 other records in <strong>Shropshire</strong>.<br />

Another find was Trochilia ilicina or Holly Speckle.<br />

This is so common that it must be under nearly every<br />

holly bush and unless it is pointed out, goes<br />

16 th April. Leader Roy Mantle. Severn Valley<br />

Country Park .Very little needs to be said about this<br />

except that the two of us found a Morel. Everywhere<br />

was devoid of fungi, which is probably why<br />

everyone kept away.<br />

19 th June. Leader Les Hughes. Haughmond Hill.<br />

Haughmond Hill is just outside Shrewsbury and is a<br />

popular place due to its elevation and the fine views<br />

it affords of western <strong>Shropshire</strong>. June is not known<br />

as a good month for fungi and only a handful of<br />

species were found<br />

including<br />

Hypholoma<br />

fasciculare<br />

(Sulphur Tuft),<br />

Inonotus hispidus<br />

(Shaggy Bracket)<br />

Hypholoma fasciculare<br />

Roy Mantle<br />

and Lacrymaria<br />

1


lacrymabunda (Weeping Widow). I. hispidus is a<br />

wonderful tawny, felty bracket which usually grows<br />

high on ash trees. L. lacrymabunda gets its name<br />

from the fact that the gills are black with a white<br />

edge and when the fungus is fresh small droplets of<br />

moisture form on them like tiny tears.<br />

10 th Sept. Leader Harvey Morgan. Oswestry<br />

Racecourse Common<br />

At this point times were hard for fungi. Many weeks<br />

without rain had left the ground dry and much<br />

searching was needed to find anything, however<br />

Harvey and the gang turned up 22 species. The<br />

Common Earthball is worth noting as earthballs are<br />

often confused with puffballs. The latter, when<br />

mature, form a small hole at the top of the ball<br />

through which the spores are puffed. The inside is<br />

packed with fibres which allow the ball to return to<br />

its original shape each time it is puffed. With<br />

earthballs, on the other hand a number of cracks<br />

form across the top when they are mature. The edges<br />

curl back leaving a cup like structure with the spores<br />

loose in the bottom. Air passing over creates eddies<br />

in the fruitbody which draw the spores out. If you<br />

pull one apart and it looks like the inside the inside<br />

of a vacuum cleaner (especially if<br />

Stropharia semiglobata<br />

Roy Mantle<br />

you have pets) then it is a puffball.<br />

Other species like Stropharia<br />

semiglobata the Dung Roundhead<br />

and Pluteus cervinus the Deer<br />

<strong>Fungus</strong> were also found. The deer<br />

fungus gets its name, not from the<br />

colour of the cap, but as those of us<br />

with microscopes will know the<br />

cystidia, that are found on the<br />

surface of the gills, have<br />

projections on them like the antlers<br />

of a deer.<br />

8th Oct. Leader Les Hughes. Granville Country<br />

Park<br />

Les did a recce before the event and found nothing<br />

and decided to call it off. We were then well into the<br />

drought.<br />

15th Oct. Leader Mike Kemp. Trawscoed Hall<br />

and Gaer Fawr<br />

This was our first foray “abroad” and we hoped that<br />

the rains in Wales had been better than the showers<br />

in the Midlands.<br />

The first area of the grounds visited was some old<br />

pasture and a range of grassland species were found.<br />

The first was the Ivory Waxcap Hygrocybe virginea<br />

var. virginea followed by Entoloma sericeum the<br />

Silky Pinkgill with its pink sinuate gills.<br />

The woodland provided a species new to me<br />

Clitocybe phaeophthalma named the Chicken Run<br />

Funnel not because of where it grows but how it<br />

smells. The red bleeding Mycena heamatopus the<br />

Burgundydrop Bonnet was found growing on a<br />

fallen branch and also found on fallen wood was<br />

Nectria cinnabarina Coral Spot in both its forms.<br />

Scleroderma verrucosum the Scaly Earthball was<br />

found<br />

pushing its<br />

way up<br />

through the<br />

tarmac<br />

path.<br />

back at the<br />

Hall and afterwards we drove to the nearby hill fort<br />

of Gaer Fawr. This means “Great Fort” in welsh. The<br />

area is a steeply wooded hill managed by the<br />

Woodland Trust. Here in the deciduous woodland on<br />

a fallen oak branch were the fruiting bodies of<br />

Bulgaria inquinans Bachelors’ Buttons looking like<br />

Pontefract Cakes strewn along the bark and on a ash<br />

branch was Daldinia concentrica King Alfred’s<br />

Cakes. Mike found and pointed out Eutypa acharii<br />

on some small sycamore branches. It was strikingly<br />

spalted and Mike had made some decorative frames<br />

from this wood. More on this later. On The way back<br />

to the hall we made a brief stop to look into<br />

Guilsfield Churchyard. Here the highlight was a<br />

group of Arched Earthstars .<br />

23 rd Oct. Leader Harvey Morgan Colemere<br />

Country Park<br />

Each year Geoffrey Kibby does an advanced fungus<br />

course at Preston Montford Field Centre and Les<br />

(who was on the course) got Geoffrey to go to<br />

Colemere on the same day. G. Kibby is an<br />

internationally renowned mycologist and editor of<br />

2


“Field Mycology”. Most of us did meet the great<br />

man but only fleetingly. I do have his list for the day.<br />

Harvey found a small bluish Mycena which<br />

Geoffrey confirmed was M. amicta. Apart from this<br />

the finds were not extraordinary, a casualty of<br />

the dry season. What a contrast to our last visit.<br />

6 th Nov. Leader Les Hughes. Dudmaston<br />

At last some rain had fallen and expectations were<br />

reasonably high and a good number of us met in the<br />

car park in the morning. We all crossed the road into<br />

Comer Wood. One of the first finds was Mycena<br />

rosea which caused a certain amount of discussion as<br />

it is very similar to M. pura. Looking at the literature<br />

separating the two is confusing with talk of umbos<br />

and campanulate caps. My own take on this is that if<br />

it is pink it is M. rosea, if there are lilac tints in the<br />

colour then it is M. pura. The microscopical<br />

differences are not significant. Spathularia flavida<br />

turned up here. It is usually found in coniferous<br />

woodland down towards the lake but in recent years<br />

it has been found here in Comer Wood. A keen eyed<br />

member also found Auriscalpium vulgare. This tiny<br />

fungus feeds on Scots Pine cones that have been<br />

pushed down into the soil. On the underside of the<br />

cap are small spines instead of gills making it a most<br />

attractive little fruitbody. The quaint club fungus<br />

Typhula quisquiliaris was also found growing, as it<br />

does, on bracken. In the afternoon Naucoria<br />

escharoides was found growing under Alder down<br />

by the boggy part of the lake. The field beyond was<br />

quite fruitful with lots of the very poisonous<br />

Clitocybe rivulosa. (Clitocybe dealbata is now also<br />

included under this name). Equally abundant was the<br />

Ivory Waxcap Hygrocybe virginea. A small Earthstar<br />

was found under some hawthorth bushes. This was<br />

taken by Harvey and he keyed it out as Geastrum<br />

floriforme. The fruitbody is hygroscopic, at maturity,<br />

and opens when moist and closes when dry. Most<br />

geastrum species open when mature and remain so.It<br />

is closely related to G. corollinum but has larger<br />

spores. As this is such a nationally rare species a<br />

specimen has been sent to RBG Kew for<br />

confirmation.<br />

19 th November. Leader Roy Mantle. Colstey and<br />

Red Wood.<br />

These woods back onto Bury Ditches and are<br />

managed by the <strong>Shropshire</strong> Wildlife Trust for the<br />

colony of Wood White butterflies that live there. The<br />

fungi that live there were very shy but Agaricus<br />

semotus was found early on. It is quite small, has a<br />

faint smell of aniseed and turns yellow with age.<br />

Lyophyllum connatum is a species which is found<br />

often at the grassy edges of paths in mixed<br />

woodland. The ones that we found were in just such<br />

a place. They are recognised by their tufted habit,<br />

pure white colour and unusual rubbery texture. There<br />

were a number of large tufts of this in the herbage at<br />

the side of the path. The broadleaved woodland was<br />

almost devoid of fungi but Stereum rugosum was<br />

found growing on the end of a fallen tree. S. rugosum<br />

grows on broadleaved wood, S sanguinolentum<br />

grows on conifers.<br />

11 th December. Leader Roy Mantle. Brown Clee.<br />

The morning proved to be damp and the afternoon<br />

positively wet and only three of us braved the<br />

weather on the hill. (It has to be said that some were<br />

braver than others). There had been some frosts and<br />

this had wiped out the grassland species with the<br />

exception of some old watery Blewits. In the<br />

protection of the trees it was a different story and<br />

here Blewits in fine condition were found. The<br />

highlights for me were the two Panellus species. P.<br />

serotinus is not uncommon but I have not seen it for<br />

a few years here. It is olive green and usually slimy,<br />

usually about 1½ inches from base to the edge of the<br />

cap, although they can get much larger. It grows on<br />

dead deciduous wood. In contrast I would rate P.<br />

mitis as uncommon, despite what the books say. It is<br />

a small white species which grows on the branches<br />

of dead conifer. The only place that I have seen it is<br />

on the Brown Clee and that was many years ago.<br />

Pannellus species are pleurotoid i.e. similar in form<br />

to the Oyster Mushroom but they have a short stem<br />

clearly delineated from the gills.<br />

First Foray Jan Arriens<br />

Vicky came out of the woods bearing an enormous whitish-grey<br />

mushroom.<br />

“Can you eat it?” I asked.<br />

“Eat it,” she said blankly. “You mean – eat it?”<br />

“Yes: is it edible.”<br />

Vicky shot a glance at her partner Luke. Luke consulted Fred,<br />

who was obviously the Top Man.<br />

“Never been asked that before,” said Fred. “It’s a clouded agaric<br />

– Clitocybe nebularis. I think you can eat it.”<br />

Now Elisabeth and I shot each other a glance. It was our first<br />

foray. All we wanted to find out was whether you could eat the<br />

stuff we kept coming across on walks. Now here were the<br />

experts and they didn't know.<br />

“I think they may upset some people, but otherwise they’re said<br />

to be quite good,” said Alan tentatively.<br />

“Here, take it,” said Vicky kindly. “Try it out at home and let us<br />

know next time what it was like.”<br />

“The point is,” said Fred, “we don't eat mushrooms.”<br />

“You – don’t – eat – mushrooms?” I said, tactfully trying to<br />

disguise a note of incredulity.<br />

“No,” replied Fred, “we identify them. We've identified two<br />

thousand five hundred in <strong>Shropshire</strong> so far. Some counties<br />

have identified five thousand. We think there may be as many<br />

as 12,500.”<br />

Alan meanwhile was busy inserting minute mushrooms – oops,<br />

fungi – into a clear plastic box with little compartments. Various<br />

small knives, a magnifying glass and dibbers dangled from his<br />

belt. Everyone apart from us – we had come with plastic bags –<br />

was equipped with backpacks. Tumbling out of these came<br />

binoculars, field guides to mushrooms, more weird and<br />

wonderful little boxes and containers, what looked like a<br />

portable microscope, labels, lunchboxes, biscuits and flasks of<br />

coffee. There may also have been some hip flasks, but we<br />

couldn't be sure.<br />

Luke had emerged from a birch grove, bearing some kind of<br />

brown mushroom. Everyone crowded round in excitement. “You<br />

can see it’s a boletus,” Fred helpfully explained to us. “If you<br />

look underneath you will see it has pores, not gills. This one<br />

could be the birch bolete, Leccinum scabrum, but the colour<br />

varies with age and it can be difficult to tell.”<br />

“I think it may be Boletus scaber,” ventured Alan.<br />

“I think that is just a former classification for the same thing,”<br />

said Fred reflectively. “So you see, even the experts can’t<br />

always agree. Anyway, the hymenium is adnate, as you can<br />

see, and it occurs only in mycorrhizal association with birch<br />

trees, which fits.”<br />

“Oh,” said Elisabeth.<br />

Novice two: “Can you eat it?”<br />

CURIOUS FUNGAL FACTS<br />

Gleanings by Ted Blackwell<br />

An Agaric, Squamanita paradoxa, is a parasite on another Agaric, Cystoderma amianthina. It<br />

completely replaces the cap of the Cystoderma but utilises its stipe which appears be unchanged as a<br />

recognisable Cystoderma stipe.<br />

When growing Shii-take mushrooms it seems to be an accepted part of the process to ‘wake up’ the<br />

mushrooms by beating logs already inoculated with the mycelial ‘spawn’. Logs may be banged with a<br />

hammer or dropped on end onto a hard surface, and this shock treatment is said to initiate primordial<br />

formation. It has not been explained why this treatment stimulates Shiitake growth, but the shock<br />

‘trigger’ is said to increase yields and facilitate more consistent fruiting on each log. An alternative<br />

shock treatment is to immerse the logs in very cold water, very much colder than the ambient air<br />

temperature.<br />

The Seventeen-year Cicada, so called because it spends 16¾ years as a pupa buried in soil and only<br />

about three months as an adult insect, is parasitised at the adult stage by a Hyphomycete fungus<br />

Massospora. The fungus invades the abdomen of the living insect and as it develops it begins to<br />

convert the insect’s internal organs to masses of spores. The unfortunate Cicada then begins to sloughoff<br />

successive segments of its abdomen thus ensuring spore dispersal and, with what seems admirable<br />

sang froid, continues to crawl around shedding spores and bits of abdomen, until only the head and<br />

thorax and one or two segments remain.<br />

The cause of a bagpiper’s persistent cough was traced to a yeast-like fungus Cryptococcus neoformans<br />

growing inside the leather bag of the pipes. This fungus is normally found in pigeon droppings.<br />

A fungus growth looking like tufts of coarse red hair or old fox pelt can sometimes be found growing<br />

over the surface of damp wood in contact with the ground, and is known in particular on pit-props in<br />

mines. It is known as Ozonium and is a sterile form of mycelium of one of several species of the<br />

Coprinus genus (domesticus, radians or micaceus).<br />

The corn smut of maize Ustilago maydis is eaten by Mexicans. The smut causes a large gall to form on<br />

some part of the plant such as leaves, stems or flowers. Galls are harvested in the early immature<br />

state before the black smut spores have developed, they are soft and when cooked are said to taste<br />

mushroomy. The Mexicans are also reported to eat the newly emerged plasmodium of the largefruiting<br />

Slime Mould, Flowers of Tan (Fuligo septica) which looks like a mass of scrambled eggs. They<br />

call it Caca da luna, the translation of which I leave to you.<br />

.<br />

According to a report in the Daily Telegraph (31 Oct 2010) truffles have sex. It has recently been<br />

discovered that the Black Truffle, Tuber melanosporum, occurs as two different mating strains,<br />

analogous to male and female. Both strains need to come together to form truffles, but often the<br />

strains occur widely apart in nature and this may partly explain why it is difficult to cultivate truffles.<br />

The renowned Victorian <strong>Shropshire</strong> naturalist and mycologist, the Revd. William Houghton (1829-<br />

1895), Rector of Preston-in-the Wield Moors, near Wellington, 1860+, reported that he had offered his<br />

white Persian cat a variety of fungi as food. It had eaten ‘with evident relish’ Hygrocybe pratensis & H.<br />

virginea, Armillaria mellea, Lepista saeva, Marasmius oreades, Collybia butyracea, Comprinus comatus,<br />

Boletus edulis & B. scaber and Hydnum repandum. But it refused ‘some known unwholesome and<br />

poison kinds’ such as Stropharia semiglobata & S. aeruginosus, Amanita muscaria, Boletus luridus and<br />

some Cortinarius. He reports his other cat a ‘common variety’ refused all fungi and seemed to say to<br />

its Persian companion “Hey, Persian lad, I dislike what’s on offer”. (The extract is from: Houghton’s<br />

'Notices of Fungi in Greek and Latin Authors' (1885).<br />

Eating the edible Saffron Milkcap and False Saffon Milkcap (Lactarius deliciosus & L. deterrimus) turns<br />

urine red. This is harmless but the unexpected discovery can cause some temporary alarm to the<br />

uninformed.<br />

Notes on a dry season Les Hughes<br />

I’d looked forward to the fungus season this year with great anticipation. I was going to make great strides in<br />

my knowledge and understanding, because I had arranged to attend three separate Field Studies Council courses<br />

at Preston Montford. The first was Identification of Summer Fungi, then a Microscopy for Mycologists course,<br />

and finally Identification of Difficult Fungi <strong>Group</strong>s. All taught by Geoffrey Kibby, one of the best mycologists<br />

in the country.<br />

Then it stopped raining. This was about the middle of May, as far as I can remember. And it didn’t start again.<br />

<strong>Shropshire</strong> got dry. Then it got drier. And drier. I walked miles looking for fungi, often without sighting a<br />

single fruit body. By the time of the first course I had walked over thirty miles in ten days, and found absolutely<br />

nothing.<br />

Course members arrived at Preston Montford from all over the country, expecting the sort of crop they were<br />

finding elsewhere. It’s a good season they said. They were to be disappointed. In order to find anything at all<br />

we had to travel to Wales, thirty miles or so, each day. We repeated this process for all three courses I attended,<br />

discovering the delights of Lake Vernwy, Gregynog, Erddig and dried material from Geoffrey’s archives in<br />

the process, but as for <strong>Shropshire</strong>? Forget it. Even the Field Studies Centre joined in the fun by selling these<br />

postcards.<br />

No, we didn’t find the camels. Although we did come across an alpaca farm one afternoon.<br />

It was the final day of all these activities. We had driven to Lake Vernwy once more to find material, and on<br />

the way home, simply as a way of filling time, and looking for future foray venues, we dropped in at the<br />

<strong>Shropshire</strong> Wildlife Trust Nature Reserve at Llanymynech<br />

Rocks.<br />

Hearing that there was Helianthemum on the site two of our more<br />

eagle-eyed members disappeared like a flash, while the rest of us<br />

strolled along finding almost nothing, the exception being a green<br />

Entoloma. Fantastic, we thought. Our friends emerged from the<br />

Helianthemum carrying a single small fruit body. A Cortinarius<br />

which no-one recognised. (Does anyone ever recognise<br />

Cortinarius on sight?) It was borne back to the lab, where the best<br />

minds toiled over the keys, and finally Geoffrey pronounced. It<br />

was Cortinarius violaceocinereus. A species never before<br />

recorded in the UK. Here it is.<br />

6


To be fair we did find lots of interesting things during these days (including for example Buchwaldoboletus<br />

lignicola), but this was in SHROPSHIRE! I don’t want to hear anyone telling me that the border with Wales<br />

runs through that quarry, OK? It’s amazing how such a samll thing can make up for so much disappointment.<br />

Yes, I know it doesn’t look much, but it gives me hope for next year’s courses. When I shall be going somewhere<br />

else.<br />

The discussion with Ted about and the<br />

spalted sycamore wood (found at Gaer Fawr – see foray<br />

reports) “sparked” an interest, and led me down a long<br />

and convoluted path. The BBC Four programme “The<br />

Science of Decay” has also prompted me to put down in<br />

writing some things which have interested me for a long<br />

time. Some delving into books and websites has helped<br />

me to “crystallise” my thoughts on these subjects. I was,<br />

by profession, an industrial chemist with a particular<br />

interest in colour.<br />

It all started for me when I learnt about Penicillin. The<br />

antibiotic properties of penicillin were first recognized by<br />

A. Fleming in 1928 when the mould ,<br />

began growing, accidentally, on a Petri dish agar plate on<br />

which a staphylococcal culture was growing. The mould<br />

produced a zone around itself which killed the bacteria by<br />

rupturing their cell walls. This is probably a mechanism<br />

which has evolved to allow moulds and other fungi to<br />

protect their food source from other organisms including<br />

other fungi.<br />

Let’s look specifically at . This produces,<br />

amongst thousands of others, muscimol which to us is a<br />

neurotoxin, i.e. it is poisonous. While these chemicals act<br />

at mammalian neurotransmitter receptors, in the case of<br />

, they are probably defensive chemicals.<br />

Because of their immediate action, muscaria chemicals<br />

would probably persuade potential predators and<br />

competitors such as mammals, insects, soil nematodes,<br />

and other fungi to dine somewhere else. We should resist<br />

the egocentric notion that these chemicals are directed at<br />

us.<br />

Nearly every cell in a human body needs cholesterol for<br />

proper membrane functioning and has the ability to<br />

manufacture it. Humans are also fortunate (and<br />

sometimes unfortunate) enough to be able to obtain<br />

significant amounts of it from their diet. The fungal<br />

equivalent is ergosterol which they can make; however,<br />

they cannot obtain it from their diet so if it is unable to<br />

produce this material it dies. Fungi have found chemical<br />

means to prevent their neighbours from producing<br />

ergosterol thus killing them off and reducing competition.<br />

We have also benefitted from this by using and modifying<br />

these chemicals to produce cholesterol regulatory drugs<br />

i.e. statins. Soon everyone on the planet will be taking<br />

these. They are life savers.<br />

These chemicals are designed to ward off other species<br />

with the same food requirements. It is interesting to<br />

speculate that each family and maybe each species must<br />

produce a different cocktail of chemicals in order to exist<br />

in a world of so many diverse and mainly antagonistic<br />

species. Could it be that the synthesis of these chemicals<br />

Notes on Chemicals and Chemical Warfare<br />

influences the colour of the fruitbody and whether it is<br />

poisonous or not?<br />

If two fungi are colonising the same piece of wood, then<br />

both will use their chemical weapons on each other. Both<br />

will want to eliminate its competitor and now another<br />

chemical comes into play, melanin. This is a black<br />

pigment found throughout the natural world. The black<br />

plumage of most birds is due to the presence of this<br />

material. In humans it is found in the hair, skin and eyes<br />

mainly as a barrier to certain wavelengths of light, most<br />

notably UV. This is why peoples from hot countries have<br />

dark skin and hair as a response to the high light levels<br />

and many hours of sunlight. This is also why light skinned<br />

people get tanned if they are exposed to too much sun.<br />

Our skins have the ability to produce melanin to act as a<br />

barrier. It is the word barrier which is significant because<br />

not only is melanin a UV barrier it is also a chemical<br />

barrier as well, and the fungi in the wood use this to<br />

provide protection from chemical attack. They deposit<br />

melanin on the junction between them and their<br />

antagonistic neighbour and so they are bounded by a<br />

dense black line. These black lines in the wood are very<br />

decorative and are used in woodturning if the fungal<br />

attack on the wood has not progressed too far. The black<br />

lines are called spalting. When I showed Ted these two<br />

pictures he identified the black fungus as<br />

and explained that the spalting lines were barriers set<br />

up between colonies of the same species to protect them<br />

from their neighbour. This is why there are gaps on the<br />

surface where the two colonies meet and there are<br />

corresponding black lines down in the wood.<br />

clear spaces between them on the surface and bounded by<br />

perithecia or only in places, this may be due to grazing by<br />

snails which are known also to find it attractive. It has<br />

never occurred to me to look microscopically at such<br />

cases to see if snail radula gnawing marks might be<br />

detected”.<br />

Why are they eaten? This is not known but ,<br />

along with some other Pyenomycetes, has been proven to<br />

have antibacterial properties.<br />

Fungi use chemicals for a variety of other reasons. Some<br />

of their strongest are used to break down wood and this<br />

has an enormous impact upon the environment. When<br />

the world was young, plants and fungi evolved together<br />

with the fungi breaking down the plant remains and all<br />

was well. Some plants began to grow taller and taller in<br />

order to out compete others for the available light. They<br />

evolved lignin in order to give them strength and they<br />

became trees. Fungi did not have the means to break<br />

down this new hard substance and consequently as the<br />

plants died they fell and accumulated in a vast layer on<br />

the ground. This had two major impacts upon the world.<br />

This layer of dead trees would become fossilised and<br />

make the coal measures. The carbon in the plants would<br />

be locked away. This had the effect of increasing the<br />

oxygen in the air from 20% to 30%. Insects breath by<br />

means of small tubes reaching down into the body and<br />

the size of the insect is governed by the amount of<br />

oxygen in the air and so insects became much larger with<br />

dragonflies having a wing span of two and a half feet.<br />

It took about 30 million years for fungi to evolve<br />

substances that would attack lignin and allow them to<br />

break down wood. Interestingly they now also had to find<br />

a way of protecting themselves from their own powerful<br />

secretions, and another chemical was utilised to<br />

strengthen their hyphae against chemical attack. They<br />

used chitin. This is a compound which is used by insects<br />

to make their exoskeletons hard.<br />

Another set of chemicals are used by fungi and they are<br />

“communication” chemicals. These may be looked upon<br />

as the stamp on a letter. They ensure that the message is<br />

delivered but do not say anything about what the<br />

message is or what the recipient will make of it. The smell<br />

of a flower says “come here”, the smell of a skunk says<br />

“go away” but the smell of a stinkhorn says different<br />

things to us than it does to flies. These molecules are not<br />

only transmitted through air but also through water, soil<br />

and even leaf litter. They are used to send messages<br />

within an organism, between organisms of the same<br />

species, and between totally different species. Many we<br />

class as pheromones and are used throughout the natural<br />

world. We live in a world of chemicals but we are woefully<br />

unequipped to appreciate most of them.<br />

Something New - Les Hughes<br />

At the end of October I had just about given up any idea of a fungus season in <strong>Shropshire</strong> (see Notes form a<br />

Dry Season). Then I got an e-amail from a friend with this photo attached. It had just appeared in his garden<br />

he said. What was it?<br />

The blue is the stain to show up the paraphyses more<br />

clearly.<br />

It’s a Peziza I replied. I’ll come and have a look. I looked.<br />

I took most of it home, and I looked for a Peziza that<br />

matched it. I failed.<br />

I took it to a SFG foray that weekend, and asked everyone<br />

to tell me what it was. We went home, and under the<br />

microscope, we agreed, a Peziza should give an amyline<br />

reaction to Meltzer’s, and it didn’t. A young Peziza<br />

vesiculosa? No-one was convinced.<br />

Under the scope it looked like this<br />

No openings at the tips of the asci. It wasn’t a Peziza.<br />

A week went by. I tried keying it out using Mycokey.<br />

I’d never tried to use the asco keys there before, and it<br />

offered Geopora, a genus I’d never even heard of. I<br />

consulted Ted Blackwell, and got by return, an positive<br />

message, and a key.<br />

The asci are operculate, uniseriate and inamyloid. The<br />

paraphyses are long and thin and twice septate. There<br />

are septate and encrusted hairs on the excipulum. The<br />

spores are smooth and guttulate, with two clear oil cells, and those measured were in the range 21.1 – 28.5 X<br />

11 – 12.5 with a mean of 24.8 X 11.7.<br />

It seemed to fit Gepora foliacea, although the spore size wasn’t perfect. It seemed a possibility. Encouraged<br />

by Ted I dried what little of it I could still find in the oven. I used the fan oven setting, and when I went to<br />

retrieve it the fan had blown it away.<br />

Back to Nigel’s garden to scrape a few remnants, this time dried a bit more carefully, and everything went in<br />

an envelope to Kew. I couldn’t believe it when only eight days later I had an e-mail from Brian Spooner (whom<br />

I thought had retired) confirming the identification.<br />

It’s a first record for <strong>Shropshire</strong>, and only 20 previous records in the UK. It’s certainly a first for Telford, but<br />

then so is nearly everything.<br />

It’s a great feeling, the first time you find something new and unusual, and get the ID right. Hope it happens<br />

again soon.<br />

Hello All,<br />

2011 was a great year for us in terms of expanding our fungal knowledge.<br />

We are keen enthusiasts and have been studying the world of fungi for around four years now. Our initial<br />

interest was based around culinary uses but we were soon taken over by the fascination and complexity of<br />

the subject.<br />

We met Roy Mantle for the second time in two years at a foray at Fenn's Moss and following a warm<br />

invitation from Roy to come along and join in the fun on more of the <strong>Shropshire</strong> group forays, we did just<br />

that.<br />

We are based near Chester so we are a little far away to make every event but we enjoyed an early morning<br />

drive to Trawscoed in October where Green Elfcup was one of many highlights of the day. A visit to<br />

Colemere later that month proved more challenging where fungi were very elusive. Finding Dudmaston in<br />

November also threw up a few 'navigational debates' on the journey but once the group were located a<br />

wonderfully productive walk ensued. Auriscalpium Vulgare was a first for us.<br />

Thanks to everyone for their warm welcome and for sharing their extensive knowledge. We look forward to<br />

much more of the same this year.<br />

The First <strong>Shropshire</strong> Mycologist and Lichenologist.<br />

Thomas Salwey (1791 – 1877), Vicar of Oswestry, 1823 to 1871.<br />

TOM PREECE<br />

The Rev. Thomas Salwey came from a very old <strong>Shropshire</strong> family, the Salweys of Orelton near Ludlow. The Salweys have been<br />

Lords of the Manor there for over 400 years. A famous Salwey was Secretary to Oliver Cromwell in the Civil Wars (1640-1650). He<br />

was one of the many Richard Salweys! The old family home is at Moor Park, Richards Castle, and Humphrey Salwey farms there<br />

today. He has done much to conserve the ancient hatchments, monuments and inscriptions in St. Bartholomew’s Church there, to<br />

a host of Salweys. About 10 miles away from the Salwey home is “Court of Hill”, between Clee Hill and Burford. This was the home<br />

(first written about in 1202) of the most famous family ever to have lived in <strong>Shropshire</strong>, the Hills. Originally from Normandy and<br />

probably everywhere chiefly remembered by the life of Rowland Hill, who was Wellington’s “right hand man” at Waterloo 1815. He<br />

lived at Hardwicke, near Hadnall, for the latter years of his life. Anne Maria Hill of “Court of Hill” married Theophilus Richard Salwey<br />

and in 1791 their son Thomas was born. He was to become the Rev. Thomas Salwey, Vicar of Oswestry, and one of <strong>Shropshire</strong>’s<br />

earliest outstanding field naturalists (Table 1 shows details of <strong>Shropshire</strong> men and others busy identifying living things in Salweys<br />

life time). Thomas entered St. John’s College Cambridge in 1810. He graduated with a B.A. in 1813, was ordained Deacon in 1815<br />

11


and Priest in 1816. He clearly was an outstanding scholar, and was a Fellow of St. John’s College from 1817 – 1828, becoming an<br />

M.A. in 1818 and gaining his B.D. degree 1827. In 1828 he became sinecure Rector of St. Florence in Pembrokeshire (as was<br />

quite common in those days). In 1823, Salwey became Vicar of Oswestry - a post he held for 48 years. If this is difficult to imagine<br />

today, it might help to say that he had been Vicar of Oswestry for 14 years when the eighteen year-old Victoria became Queen in<br />

1837, George IVth preceding her as Sovereign. It was a time of candles, oil-lamps, and horses everywhere. Railways and motor<br />

cars were things of the future. How Thomas Salwey became obsessively interested in fungi, and more especially in lichens, is not<br />

known. One might speculate that, like Charles Darwin of Shrewsbury, he experienced, at Cambridge, the remarkable influence of<br />

Professor J.S. Henshaw, the Professor of Botany there at that time. There were living at the same time as Salwey important<br />

<strong>Shropshire</strong> mycologists (Table 1). How much he knew about or contacted these men is not known, except in the case of another<br />

clergyman, Rev. W.A. Leighton (Table 1), son of a Shrewsbury Inn-Keeper. Leighton was definitely influenced like Darwin by<br />

Henshaw at Cambridge, and he dedicated his 1840 (flowering plant) Flora of <strong>Shropshire</strong> to him, describing himself as “his grateful<br />

pupil”. Leighton was, briefly, the Curate of St. Giles Church in Shrewsbury, but devoted the rest of his life firstly to flowering plants,<br />

and later, for many years, to lichens. In 1838 Salwey was sending many named specimens of microscopic fungi to Kew. These<br />

included Puccinia caricina on the rare host Carex elata from Morda Pool near Oswestry. Also, from places “in Oswestry” he sent<br />

P.caricina on nettle. Puccinia adoxae on Town Hall Clock, and Puccinia calcitrapae on Knapweed, as well as other rusts from his<br />

vicarage garden on poplar, birch and roses. The smut fungus on grasses, Ustilago salvei Berkely & Broome, was named in his<br />

honour in 1850. His specimen, collected in 1847, on Cock’s-foot grass at St. Martins Guernsey, is in the Kew herbarium and is the<br />

type specimen of this fungus. It is now called Ustilago striiformis, and is found on many genera of grasses in Britain today. He<br />

produced a list of fungi from around Oswestry (and a long list of lichens) in 1855 in Cathralls History of Oswestry. Identifying the<br />

spores of rust fungi and of lichens necessitates microscopy. The use by naturalists of a microscope in Salweys time was directly<br />

the result of Robert Browns description and illustration of cell nuclei for the first time in 1831. By 1841, the price of a microscope<br />

was “reasonable”. Even before that, in 1834, J.V.M. Dovaston was grumbling away at West Felton, near Oswestry, that “naturalists<br />

here are becoming so damned learned they will not look at flowers; nothing will go down with them, but a minute moss, lichen or<br />

fungus”. Lichens and microscopy took over Salweys life as a naturalist, and between 1823 and 1863 he produced lists of lichens,<br />

not only for the Oswestry area, but also for Wales and Great Britain. He made important lichen collections from Guernsey, the Isle<br />

of Wight, and more specifically, from Barmouth, Harlech and Dolgellau. All his specimens were shared with Rev. W.A. Leighton. He<br />

prepared bound collection of lichen specimens for various museums (as was the custom then). One of these collections is in Bolton<br />

Museum. He corresponded with the eminent lichenologists of this day (long handwritten letters!) These (some of which are at the<br />

British Museum (Natural History) show he was au fait with the lichen literature (English and Foreign). It was his unstinted<br />

contributions to Rev. W.A. Leighton’s two books on lichens which remain significant, and remarkable, for us today. In 1851<br />

Leighton produced a superbly illustrated book of perithecial lichens “The British Species of Angiocarpous lichens Elucidated by<br />

their sporidia” using a number of specimens provided by Salwey. It contains coloured transverse sections of lichen thalli, and<br />

coloured groups of individual spores, prepared “using a large and powerful microscope of the best construction made by Powell &<br />

Leland, Opticians, of London”. A good example from this book would be the first lichen described in it – called by Leighton<br />

Sphaerophorum coralloides. Two types are given – the first from “<strong>Shropshire</strong>, near Oswestry, Rev. T Salwey” and the second from<br />

“Craigforda, near Oswestry, Rev. T. Salwey”. These two types are now known as Sphaerophorus fragilis and Sphaerophorus<br />

globosus. Further on in the book, a lengthy description of a lichen by Salwey written in 1844 is included verbatim. Salwey was<br />

seldom in Oswestry after 1840 – being in Guernsey, Jersey or the Isle of Wight. He also stayed at places on the Welsh coast,<br />

including Barmouth and Harlech, for prolonged periods. Curates did the work at Oswestry Parish Church from this date until he<br />

retired. In 1871, Leighton produced a hugely significant and popular book – The Lichen Flora of Great Britain, Ireland and the<br />

Channel Islands. The text is replete with detailed references to Salwey’s lichen collections – perhaps some 300 different lichens.<br />

This book sold out quickly, a second edition was printed in Shrewsbury in 1872 and a third edition in 1879. Some of the lichens<br />

therein are from the old Salwey home (see above) at Richards Castle, near Ludlow, so Salwey must have gone there from time to<br />

time. One lichen named after him has (remarkably!) retained its name to the present day. This is Acrocordia salweyi (Leighton ex<br />

Nylander). A.L. Smith. which has large black perithecia, found on soft rocks, mortar and cement, especially in S.E. England.<br />

Another example of the value of Salwey’s work is revealed in a 2008 paper (in Bull. British Lichen Society, 102) by Ann Allen about<br />

the re-discovery of Lobaria pulmonaria and Teloschistes species in the Channel Islands. The author examined Salwey’s 1847<br />

Guernsey collection in the herbarium of the Natural History Museum. He called it, then, Sticta pulmonaria. Salwey’s 1877 collection<br />

from Sark of Teloschistes chrysopthalmus is also mentioned. Apart from lists of his collections and their locations, Salwey did not<br />

produce papers similar to those we read today. A very good account of his church work during his early years as Vicar of Oswestry<br />

12


is given in a recent small book by John Pryce-Jones called An Oswestry Miscellany (2007). Llanforda Press. Salwey produced 2<br />

books as Vicar, Duties of a Christian Magistrate (1835) and Gospel Hymns in 1847. There is a fine stained-glass window dedicated<br />

to him in his Oswestry Church. Probably this Vicar, scholar, mycologist and lichenologist would have been pleased with the Latin<br />

inscription on the brass plaque below his window. Polished for 135 years by Oswestry ladies, some words are illegible today! Even<br />

so, generations must have looked at this window, unaware of his massive contribution to the study of lichens and mycology<br />

generally in Britain. The brass reads: =<br />

“Thomas Salwey S.J.B. (=Sanctae Theologiae Baccalaureus = B.D. today) Hujusce Ecclesiae per annos XLIX vicarii laborum<br />

pastoralium ne – memoria fenestrum – ornaberunt fillii, Ann. Dom. 1876”<br />

(roughly translated, with the help of many friends):=<br />

“Thomas Salwey, B.D. Vicar of this Church for 49 years. This window was embellished by his children 1876”<br />

This may be the only stained glass window devoted to a biologist in Britain. We can gaze at it today, and wonder at his<br />

achievements with his microscope so long ago.<br />

Rare Finds<br />

A new site has been discovered in <strong>Shropshire</strong> for Batteraea phalloides the Sandy<br />

Stiltball. This is on the Red Data and BAP lists and is a nationally rare species<br />

with only a few records for the British Isles. With over twenty fruiting bodies, in<br />

various stages, this is a major site. This was reported by Jefny and David<br />

Ashcroft. David is a natue photographer a found this whilst cycling around the<br />

Worfield area near Bridgnorth.<br />

Tom has found a fungus growing on moss in his garden This has been confirmed<br />

by Kew as Rimbachia neckerae. This is a small bell or helmet shaped fungus that<br />

only has 9 previous records for the UK. 3 of these records are from <strong>Shropshire</strong>.<br />

Please visit our website on www.shropshirefungusgroup.org. If there is anything else that you would like to<br />

see there let me or Les know.<br />
