will further enhance yields for each strain. I
find this formula to be highly productive and
recommend it highly.
The base substrate is composed of fast-decomposing hardwoods, such as alder, poplar,
and cottonwood in contrast to the slow-rotting
woods like oak and ironwood. If these types of

quick-rotting woods are unavailable, deferment should first be made to the tree types upon
which the mushroom species natively inhabits.
Most of the photographs in this book are from
blocks made with this basic formula.

I have devised the following fruiting forinula utilizing hardwood sawdust, hardwood
chips, and a nitrogen-rich supplement, in this
case rice bran. Water is added until 65-75%
moisture is achieved, a few percentage points
below saturation.

commodity and not available as a base component, please refer to Chapter 18.

The Sawdust/Bran Fruiting
100 pounds sawdust
50 pounds wood chips (1/2-4 inches)
40 pounds oat, wheat, or rice bran
5-7 pounds gypsum (calcium sulfate)*

By dry weight, the fraction of bran is ap-

proximately 20% of the total mass. By volume
