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 />

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 />
3
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 />

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 />
