MATERIALS FOR FORMULATING A FRUITING SUBSTRATE
pasteurized for several hours. Because peanut
shells form subterraneously and are in ground
contact, they should be thoroughly washed be-

fore pasteurization. Sterilization may be
required if pasteurization is insufficient. The addition of 5% gypsum (calcium sulfate) helps keep

the substrate loose and aerated. Oyster mushrooms, in particular, thrive on this material.

terns to, from and within the growing rooms are
crucial. Supplementation of outdoor beds risks
competition from contaminants and insects.
If supplementing a substrate, the sterilization

cycle should be prolonged. Sterilization must
be extended from 2 hours for plain sawdust at
15 psi to 4 hours for the same sawdust supplemented with 20% rice bran.

Supplements
Supplementing the substrate can boost yields.

A wide variety of protein-rich (nitrogenous)
materials can be used to enhance the base sub-

strate. Many of these are grains or their
derivatives, like rice, wheat or oat bran, ground
corn, etc. Supplementing a substrate, such as
straw or sawdust, changes the number and the
type of organisms that can be supported. Most of
the raw materials used for growing the mush-

rooms listed in this book favor mushroom
mycelium and are nitrogen-poor. Semi-selectivity is lost after nitrogen supplements are added,
but ultimately mushroom yields improve. Therefore, when supplements are used, extra care is
required to discourage contamination and insure
success. Here good hygiene and good flow pat-

ful because the cultivator offsets the upward
spiral of temperature. Simply spacing spawn
bags or jars apart from one another, and lowering spawn room temperatures as thermogenesis
begins, can stop this catalytic climb. For many
of the gourmet wood decomposers, a temperature plateau of 75-85°F. (24-29° C.) is ideal.
The following supplements can be added at
various percentages of total dry mass of the bulk
substrate to enhance yields.
