Substrates for Fruiting: Broadly adaptive,

producing mushrooms on a great array of organic debris. The substrate materials proven to

result in the greatest yields are the cereal

(wheat, rice) straws, hardwood sawdusts, corn

stalks, sugar cane bagasse, coffee waste
(Martinez et al., 1985), pulp mill sludge

(Mueller & Gawley, 1983), cotton waste and
numerous other agricultural and forest waste
by-products. Royse & Bahier (1988) found that
the addition of 20% alfalfa hay to wheat straw
increased yields substantially. In their studies,
yields peeked when a combination of wheat
straw, alfalfa, and delayed release nutrients
were employed. (The effect of delayed release
nutrients on Oyster mushroom yield is discussed in detail by Royse & Schisler, 1987a,
1987b.) Alfalfa hay, as any compost maker
knows, is considered "hot" because of its elFigure 288. P. pulmonarius truiting from 25 lb. bag
