Dry Pleurotus ostreatus - Sporeless Brown Oyster Mushroom

Scientific Name: Pleurotus ostreatus

Common Names: Brown Oyster, Wood Oyster, Tree Oyster, Oyster Shelf, Straw Mushroom, Hiratake, Tamogitake

Description:  A large, tender, delicious mushroom with a beautiful brown colored cap, this cultivar was cloned from local Southwestern Ontario specimens.  Brown oyster and other P. ostreatus species are some of the easiest to grow because they fruit using many substrates over a wide range of temperatures:  Hardwood, straw, and coffee grinds can produce huge yields of beautiful fruitbodies.  Brown Oyster is the best choice for the beginner.  Lower temperatures and higher light lead to darker cap color, while high temperatures and low light can produce an almost albino form.  This cold temperature variety is a good choice for spring/fall outdoors or winter in the greenhouse.  This variety has the added benefit of lower/delayed spore formation, allowing for larger fruitbodies to form and less spore accumulation on fans/filters.
