Available Strains: Strains from the wild, unlike those of Pleurotus, rarely produce under

artificial conditions. Of the strains I have tested
which have been obtained from culture libraries, deposited there by taxonomically
schooled, non-cultivator mycologists, 90% of
them do not fruit well on sterilized wood-based
substrates. Therefore, screening and development of strains is necessary before commercial
cultivation is feasible. Strains which produce

fruitbody initials in 30 days are considered
very fast. Most strains require 60-120 days of
incubation before primordia formation begins.
Mycelial Characteristics: White, longitudinally

linear, eventually thickly cottony on enriched agar
media, non-rhizomorphic. The mycelium grows
