Description: A substantial mushroom, often up
to 12 inches in diameter. Cap convex, to hemispheric, expanding to plane at maturity,
smooth, yellowish gray to grayish brown to tan
to dingy brown, darker towards the center. Gills

gray at first, becoming chocolate brown with
spore maturity. Stem white, adorned with a well

developed membranous ring, usually colored
brown from spore fall.

Natural Habitat: Growing saprophytically, often in clusters, on stumps in the southeastern
United States and southern Europe. Preferring
hardwoods, especially cottonwoods, willows,
poplars, maples, box elders, and in China on
tea-oil trees.

Distribution: Not known to occur in North

Figure 193.20 days after inoculation, primorida voluntarily form on malt extract agar.

America outside of the southeastern states of
Mississippi, Louisiana and Georgia. Common
across southern Europe and in similar climatic
zones of the Far East.

Microscopic Features: Spores smooth, ovoid to slightly ellipsoid, brown, 9-11 x 5-6. 5(7)p, lacking
a distinct germ pore. Clamp connections present.

Available Strains: Strains are commonly available from culture libraries. Most strains cloned from
wild specimens produce on hardwoods.
Mycelial Characteristics: Longitudinally linear, becoming cottony, usually not aerial. White at first,
soon becoming spotted brown, and eventually tan brown. Primordia usually form on malt extract agar

Fragrance Signature: Mealy, farinaceous, but not pleasant.
Natural Method of Cultivation: Stumps of the above-mentioned trees. Outdoor wood chips beds also
produce, much in the same manner as for the cultivation of Stmpharia rugoso-annulata.

Recommended Courses for Expansion of Mycelial Mass to Achieve Fruiting: Petri dish cultures
blended via Eberbach stirrers to create liquid inoculum which is, in turn, injected into sterilized grain.
This grain spawn can be used to make sawdust spawn for outdoor inoculations or for inoculating directly into supplemented, sterilized, hardwood sawdust.

Suggested Agar Culture Media: Malt Yeast Peptone Agar (MYPA), Potato Dextrose Yeast Agar
(PDYA), OatmealYeastAgar (OMYA) & Dog FoodAgar (DFA).
1st, 2nd and 3rd Generation Spawn Media: Cereal grains (rye, wheat, milo, sorghum, etc.) for 1st
