376 GROWTH PARAMETERS
Suggested Agar Culture Media: MYA,
MYPA, PDYA orDFA.
1st, 2nd & 3rd Generation Spawn Media:
Grain-to-grain expansions. The final spawn
medium can be another generation of grain
spawn, or alternatively sawdust. The sawdust
spawn can be used to inoculate supplemented
sawdust (i.e. sawdustlchipsfbrafl) or plugs for
outdoor cultivation on stumps or partially buried,
vertically positioned, large diameter
hardwood logs. Considering the long incubation
period, cultivators are well advised to
weigh the advantages of creating another generation
of sawdust spawn. The advantage of the
grain spawn-inoculated bags is that they produce
several weeks earlier than do the
sawdust-inoculated blocks. However, the quality
of colonization is better provided by spawn
made of sawdust than from grain.
Substrates for Fruiting: Supplemented hardwood
sawdust, particularly oak, poplar,
cottonwood, elm, willow and alder. Alder and
poplar stumps are less likely to support outdoor
fruitings, given the hold competitors like
Pleurotus ostreatus and allies have on that niche. For indoor cultivation, yields vary substantially between
various wood types. Oak is generally preferred, although strains growing on conifers are being
developed.
Recommended Containers for Fruiting: Polypropylene bags with filter patches for k

air exchange.
Polypropylene bottles and buckets have also been used.
Yield Potentials: 1/2 to 2lbs. mushroom per 5-7 lbs. of sterilized, enriched hardwood sawdust.
Harvest Hints: Relative humidity should be carefully lowered as the fruitbody develops to prevent
bacterial blotch. Over-watering can quickly cause the fruitbodies to abort. The thick base should be
cut to remove substrate
debris. Mushrooms wrapped in rice paper, and then refrigerated, have an extended
shelf life up to two weeks at 35° F. (1-2.° C.)
Form of Product Sold to Market: Fresh and dried mushrooms for the gourmet market. High quality
tablets are being marketed in the United States by Maitake, Inc. Fungi Perfecti is currently selling a
tea ("Stamets Olympic Rainforest Mushroom Tea") containing dried fruitbodies of this mushroom.
(For the addresses of these two companies, please refer to the Resource section on page 495.) Fresh
Maitake has been inexpensive and commonly available throughout the food markets of Japan. In
