Suggested Agar Culture Media: MYPA,
PDYA, OMYA or DFA. Optimal growth seen at
pH 5.5-6.5.

1st, 2nd & 3rd Generation Spawn Media:
Rye, wheat, milo, sorghum, corn, & millet.
Sawdust spawn is not needed for indoor cultivation methods. However, sawdust spawn is
ideal in the inoculation of stumps and logs in
outdoor settings.

Substrates for Fruiting: A wide array of agricultural and forest waste products can be used,
including but not limited to: straw (wheat, rye,
oat, rice, and barley straw); corn stalks, sugar
cane bagasse; coffee pulp; banana waste; cot-

ton waste & cottonseed hulls; hardwood
sawdusts; paper by-products; soybean waste;
palm oil by-products; agave waste; and even
the pulp remaining from tequila production!

for maximum biomass production. (See ElKattan et al., 1990.)
Martinez et al. (1985) reported yields of 132% biological efficiency (4 flushes) from coffee pulp
that was fermented for 5 days, pasteurized, and inoculated with wheat grain spawn. Further, they
found residual caffeine from the spent substrate was reduced by more than 90%. (Caffeine represents
a significant toxic waste to streams in coffee growing regions of the world.) Martinez-Carrera(1987)
validated the results with yields in excess of 100% biological efficiency on the same substrate and
presented the first model for utilizing this abundant waste product.
Platt et al. (1982) published studies on the utility of cotton straw as a substrate for this mushroom.
Their yields average 600-700 grams per kilogram of dry cotton straw, in other words 60-70% biological efficiency.

Yield Potentials: 75-200% biological efficiency, greatly affected by the size of the fruitbodies harvested, and the number of flushes orchestrated.
Harvest Hints: Mushrooms should be picked when young, and preferably in clusters. Once the gills
produce abundant spores, storageability rapidly declines. Workers should wear filter masks effective
down to 7 microns to eliminate the inhaling of spores. Mushroom surfaces should be slightly dry at
harvest. Mushrooms should be chilled first to 350 F (1-2° C.) and then placed into end-user containers (for restaurants or consumers) and covered with breathable, anti-condensate plastic film.
