Auricularia. They are also being utilized with some modifications by commercial shiitake growers in
the United States. The development of these mushroom specific substrates follows certain well defined guidelines.

The basic raw material is cellulose, a major constituent of sawdust, straw, cardboard or paper
wastes, wood chips, or other natural plant fibers. Any of these materials should be chopped or
shredded, but never so finely as to eliminate their inherent structural qualities. This cellulosic base
comprises approximately 80% of the total substrate mixture.
To these basic substrate materials are added various nutrient supplements and growth stimulators in meal or flour form. By supplying proteins, carbohydrates, vitamins and minerals, the supplements serve to enhance the yield capabilities of the substrate base. Protein sources include concentrates like soya meal or soya flour, wheat germ and brewer's yeast. The most suitable carbohydrate
sources are starchy materials such as rice, potatoes, corn and wheat. Some supplements are well
balanced and provide both carbohydrates and proteins. Examples of these are bran, oatmeal and
grains of all types. The number of possible supplements is extensive and need not be limited to
those listed. The supplements comprise approximately 8-25% of the total dry weight. The addition
of gypsum at a rate of 5% of the dry weight can improve the structure and porosity. It should be
considered an optional ingredient.

Japanese growers of Flammulina ve/utipes, Auricularia auricula and allies, and Pleurotus
ostreatus have a standard substrate formula consisting of 4 parts sawdust and 1 part bran. The saw-
