Cropping Cycle:
2 crops, 3-4 weeks apart.

ing a luxuriantly satin-like mycelia on sterilized malt agar media. The mycelium is white, cottony at
first, soon silky rhizomorphic, usually radiating outwards with diverging fans from the site of inoculation. Mycelium often, but does not necessarily, bruises bluish.

Fragrance Signature: Sour, unpleasant, nearly nauseating to some people, farinaceous, and reminiscent of spoiling corn.
Natural Method of Cultivation: This mushroom conforms to essentially the same strategy as Stmpharia
rugoso-annulata. (See growth parameters for that species.) Sawdust spawn is broadcasted into hardwood
or conifer (Douglas fir) chips which have been laid down outdoors in a partially shaded environment. The
wood chips should be variable in size, ranging from 1/8th inch in diameter to 4 inches in length.

Recommended Courses for Expansion of Mycelial Mass to Achieve Fruiting: Liquid inoculated
grain spawn to 50:50 sawdust/wood chips used as spawn into outdoor beds.

Suggested Agar Culture Media: MYA, PDYA, OMYA or DFA.
