The cultivation of other edible fungi is a rapidly growing industry m Ontario and Canada. In Ontario during 1984 there was no measureable production of oyster mushrooms. However in 1985 production increased to about 2,300 kg per week and in 1986 the production was between 3,000-4,500 kg per week. During 1987, an increase in production to 4,500-5,000 kg per week is anticipated. The estimated production of oyster mushrooms Canadawide for 1987 will be between 7,000-9,000 kg per week. There are at least three species of oyster mushrooms presently being cultivated Pleurotus ostreatus, Pleurotus pulmonarius, and Pleurotus sajor-caju.

Wheat straw is the principal substrate for oyster mushroom growing in Ontario. Although adequate production can be achieved through use of wheat straw, the addition of supplements to a base material has substantially increased the yield per unit weight (Laborde et al., 1985). Mushroom cultivation is a controlled biological process that must utilize the available waste or resources in the area of its cultivation. This paper presents the response of Pleurotus ostreatus to some available resources or agricultural waste materials in Southern Ontario, Canada.
