Oyster oyster or oyster mushroom are the most cultivated member of the oyster mushroom genus. It is extremely suitable for cultivation due to its unpretentiousness to climatic conditions and tenacious mycelium suitable for storage.
Oyster oyster hat: Round-eccentric, funnel-shaped, ear-shaped, usually with tucked edges, matte, smooth, can take on any shade in the range from light ash to dark gray (there are light, yellowish, and “metallic” options). Diameter 5-15 cm (up to 25). Several hats often form a fan-shaped, tiered structure. The flesh is white, dense, becoming quite hard with age. The smell is weak, pleasant.
Oyster oyster slices: Descending along the stem (as a rule, they do not reach the base of the stem), sparse, wide, white when young, then grayish or yellowish.
Spore powder: White.
Stem of oyster mushroom: Lateral, eccentric, short (almost imperceptible at times), curved, up to 3 cm long, light, hairy at the base. Older oyster mushrooms are very tough.
Spread: Oyster mushroom grows on dead wood and on weakened trees, preferring deciduous species. Mass fruiting, as a rule, is noted in September-October, although under favorable conditions it may appear in May. The oyster mushroom courageously fights frosts, leaving behind almost all edible mushrooms, except for the winter mushroom (Flammulina velutipes). The “nesting” principle of the formation of fruiting bodies actually guarantees high yields.
Similar species: Oyster oyster mushrooms can, in principle, be confused with oyster mushrooms (Pleurotus cornucopiae), from which it differs in a stronger constitution, a darker color of the cap (except for light varieties), a short stem and plates that do not reach its base. From whitish oyster mushroom (Pleurotus pulmonarius), oyster oyster mushroom is also distinguished by a dark color and a more solid structure of the fruiting body; from oak oyster mushroom (P. dryinus) – the absence of a private bedspread. Inexperienced naturalists may also confuse oyster oyster mushroom with the so-called autumn oyster mushroom (Panellus sirotinus), but this interesting fungus has a special gelatinous layer under the skin of the cap that protects the fruiting body from hypothermia.
Edibility: Mushroom edible and delicious even when young.. Artificially cultivated (who goes to the store, he saw). Mature oyster mushrooms become tough and tasteless.
