dust transfers are common when growing
Shiitake, Nameko, Oyster, Maitake, Reishi or
King Stropharia. Once grown out, each of these
bags can generate 5-10 more sawdust spawn
bags (St to S2). No more than two generations
of expansion are recommended in the production of sawdust spawn.

IV. Formulating the Fruiting Substrate:
The fruiting substrate is the platform from
which mushrooms arise. With many species,
this is the final stage where mushrooms are produced for market.The formulas are specifically
designed for mushroom production and are of-

ten nutrified with a variety of supplements.
Some growers on bulk substrates expand the
mycelium one more time, although I hesitate to


recommend this course of action. Oyster cultivators in Europe commonly mix fully

colonized, pasteurized straw into ten times
more pasteurized straw, thus attaining a tremen-

dous amount of mycelial mileage. However,
success occurs only if the utmost purity is main-

tained. Otherwise, the cultivator risks losing
everything in the gamble for one more expansion.

This final substrate can be amended with a

variety of materials to boost yields. With
Shiitake, supplementation with rice bran
(20%), rye flour (20%), soybean meal (5%),
molasses (3-5%), or sugar (1% sucrose) signifi-

cantly boosts yields by 20% or more. (For more
information the effects of sugar supplementation on Shiitake yields, see Royse et al., 1990.)
