Cereal Straws For the cultivation of Oyster
mushrooms, cereal straws rank as the most us-

able base material. Wheat, rye, oat and rice
straw perform the best. Of all the straws, I pre-

fer wheat. Inexpensive, readily available,
preserving well under dry storage conditions,
wheat straw admits few competitors. Further-

more, wheat straw has a nearly ideal shaft
diameter which selectively favors the filamentous cells of most mushrooms. Chopped into
1-4 inch lengths, the wheat straw needs only to
be pasteurized by any one of several methods.
The approach most easily used by home cultivators is to submerge the chopped straw into hot
water (160°F., 710 C.) for 1-2 hours, drain, and
inoculate. First, fill a metal barrel with hot tap
water and place a propane burner underneath.
(Drums should be food grade quality. Do not

use those that have stored chemicals.) A

a cement slab or plastic sheeting to a depth of
no more than 24 inches.The straw is wetted and

looser substrate whereas finer straws create
a denser or "closed" substrate. A cubic foot
of wetted straw should weigh around 20-25
lbs. Substrates with lower densities tend to
perform poorly. The cultivator must design a
substrate which allows air-exchange to the
core. Substrate dynamics are determined by
a combination of all these variables.

turned for 2-4 days, and then loaded into a
highly insulated box or room. Steam is introduced, heating the mass to 160° F. (710 C.) for
2-4 hours. (See Chapter 18 for these methods.)
The semi-selectivity of wheat straw, especially after pasteurization, gives the cultivator a

two-week "window of opportunity" to establish the gourmet mushroom mycelium. Wheat
straw is one of the most forgiving substrates
with which to work. Outdoor inoculations of
pasteurized wheat straw with grain spawn, even

Paper Products (Newspaper, Cardboard, Books, etc.) Using paper products as
a substrate base is particularly attractive to

those wishing to grow mushrooms where
sawdust supplies are limited. Tropical is-

when the inoculations take place in the openair, have a surprisingly high rate of success for
home cultivators.
Rye straw is similar to wheat, but coarser.
Oat and rice straw are finer than both wheat

examples. Paper products are made of pulped
wood, (lignin-cellulose fibers), and therefore

and rye. The final structure of the substrate
depends upon the diameter and the length of
each straw shaft. Coarser straws result in a
