rice, oat and sorghum straws are the best. Hay,

resplendent with abundant bunches of seed
kernels, should not be used as the grain kernels tend to contaminate. However, limited
numbers of grain kernels generally boost
yields. Royse (1988) found that yields of Oyster mushrooms from wheat straw are
enhanced by the addition of 20% alfalfa without increasing the risk of contamination.Alfalfa,
by itself, is "too hot" to use because of its elevated nitrogen content. Straw supports all the

spp.) mushrooms also thrive on straw-based
substrates, often benefiting from modest supple-

of these species are discussed further on, in

Heat Treating the
Bulk Substrate
Bulk substrates like straw are generally pas-

teurized (as opposed to sterilized) and upon
cooling, inoculated with grain spawn. Pasteur-

ization selectively kills off populations of
temperature-sensitive micro-organisms. The
population left intact presents little competition to the mushroom mycelium for
approximately two weeks, giving ample op-

portunity for the mushroom mycelium to
colonize. If not colonized within two weeks,
the straw naturally contaminates with other
fungi, irrespective of the degree of pasteuriza-
