Grain Culture/43

WHEAT: Works equally well as rye for spawn making and fruitbody production.
WHEAT GRASS and RYE GRASS SEED: Both have many more kernels per gram than
grain. The disadvantage of seed is the tendency to lose its moisture and its inability to separate into individual kernels, making it difficult to shake. (Rye grass and wheat grass seed are
widely used to promote sclerotia formation in Psilocybe fampanensis, Psilocybe mexicana
and Psilocybe armandii. Perennial or annual can be used although annual is far cheaper.
See the species parameters for these species in Chapter Xl.)

RYE: Its availability, low cost and ability to separate into individual kernels are all features
recommending its use as a spawn and fruiting medium.

GRASS SEED

In a single gram of commercial rye, Secale cereale, there is an estimated cell count of
50,000-100,000 bacteria, more than 200,000 actinomyces, 12,000 fungi and a large number of
yeasts. To sterilize one gram of grain would require, in effect, the destruction of more than 300,000
contaminants! In a spawn jar containing in excess of a hundred grams of grain, and with the addition
of water, the cell population soars to astronomical figures.
Of all the groups of these organisms, bacteria are the most pernicious. Bacteria can divide
every twenty or so minutes at room temperature. At this rate, a single bacterium multiplies into
