Oyster mushroom (Pleurotus ostreatus)
Synonyms:
Oyster mushroom or common oyster mushroom is the most cultivated representative of the genus oyster mushroom. It is extremely convenient for cultivation due to its unpretentiousness to climatic conditions and tenacious mycelium, suitable for storage.
Oyster oyster mushroom cap: Rounded eccentric, funnel-shaped, ear-shaped, usually with rolled edges, matte, smooth, can take any shades in the range from light ash to dark gray (there are light, yellowish, and "metallic" options). Diameter 5-15 cm (up to 25). Several caps often form a fan-shaped, multi-tiered structure. The flesh is white, dense, becomes rather tough with age. The smell is weak, pleasant.
Oyster oyster mushroom plates: Descending along the stem (as a rule, do not reach the base of the stem), rare, wide, white in youth, then grayish or yellowish.
Spore powder: White.
Oyster leg of oyster mushroom: Lateral, eccentric, short (sometimes almost invisible), curved, up to 3 cm in length, light, hairy at the base. Older oyster mushrooms are very tough.
Distribution: Oyster mushroom grows on dead wood and weakened trees, preferring deciduous species. Mass fruiting, as a rule, is observed in September-October, although under favorable conditions it can appear in May. Oyster mushroom bravely fights frost, leaving behind almost all edible mushrooms, except for winter mushrooms (Flammulina velutipes). The "nesting" principle of the formation of fruit bodies actually guarantees a high yield.
Similar species: Oyster mushroom can, in principle, be confused with oyster mushroom (Pleurotus cornucopiae), from which it differs in a stronger constitution, a darker cap color (except for light varieties), a short stem and plates that do not reach its base. Oyster mushroom is also distinguished from whitish oyster mushroom (Pleurotus pulmonarius) by its dark color and more solid structure of the fruiting body; oak oyster mushroom (P. dryinus) - lack of a private bedspread. Inexperienced naturalists may also confuse oyster mushroom with the so-called autumn oyster mushroom (Panellus sirotinus), but this interesting mushroom has a special gelatinous layer under the skin of the cap that protects the fruiting body from hypothermia.
Edible: The mushroom is edible and even tasty when young. Artificially cultivated (whoever goes to the store saw it). Elderly oyster mushrooms become tough and tasteless.

Author's notes: Surprisingly, but true: I first encountered the most common oyster mushroom only when I myself wanted it. Deliberately collided. I remembered in early September that I had never actually seen oyster mushroom in the field (shame!), And went in search of
I had to search for a long time: only on the way back, passing by a huge broken willow growing (or rather, rotting) at my gate, I noticed the strange gray "ears" defiantly bulging on the chopped trunk ...
Unlike its nondescript counterparts, oyster mushroom made a very serious impression on me. It does not look like a dried pig's ear, or a swollen overgrown chanterelle. Heavy "nests" that do not disintegrate during collection, large cozy burdocks of caps, dense white flesh, homerically huge worms ... all these signs set you up for a serious mood. Indeed, not every mushroom knows how to present itself in such a way that you want to grab a whole "nest" (with both hands, you can't drag it off with one) and carry it to show your neighbors - as I actually did.
And oyster mushroom nests can cleverly wriggle out from under the knife and fall with all their weight on the head of a hurried collector, without splitting at all.

The mushroom pulp is white and has a flour smell. In young specimens, it is soft and tender, and in ripe mushrooms it becomes rough.
The stem of the mushroom is white (yellow in some specimens), comes from the central part of the cap. In mature mushrooms, it becomes lateral.
The diameter of the cap is 3-6 cm, but in some specimens it can reach 10 cm. In young mushrooms, the cap is thyroid, in mature fruiting bodies a large depression appears on it, and a little later the cap becomes funnel-shaped, and its edges are lobed.The bright lemon color of the cap of overripe, old mushrooms fades and becomes whitish.
The lamellar hymenophore consists of frequent and narrow plates, the width of which is 3-4 cm. They are slightly pinkish in color, descending to the pedicle in the form of lines. The spore powder is white in color, but in many specimens it has a pink-purple hue.
Season and habitat of the mushroom
Lemon oyster mushroom (Pleurotus citrinopileatus) grows in the southern part of Primorsky Krai, in mixed (with coniferous and broad-leaved trees) forests, on living or dead elms. This mushroom also develops well on elm deadwood, and in the northern regions and the middle vegetation zone it is also found on the trunks of birches. Lemon oyster mushrooms are widespread in the southern parts of the Far East; they are well known to the local population there and are used by them as edible mushrooms. Begins to bear fruit in May and ends in October.
Edibility
Lemon oyster mushroom (Pleurotus citrinopileatus) is an edible mushroom. Possesses good taste, it is used salted, boiled, fried and pickled. Lemon oyster can be dried. However, in ripe fruit bodies, only the cap is suitable for eating, since the stem of the fruit body becomes fibrous and rough. In some specimens, a part of the cap above the leg is also endowed with such qualities, so it also has to be cut out before cooking the mushrooms for food. Grown in artificial conditions for the purpose of implementation.
Other information about the mushroom
This oyster mushroom was named lemon yellow for its characteristic cap color, similar to the color of a ripe lemon. The mushroom retains its bright yellow color throughout its entire growth. Lemon oyster mushroom substrate mycelium is resistant to cold and frost. The mushroom itself is thermophilic, has a moderate taste properties, becomes a real decoration for the garden.

Growing at home and in the country
There are two ways to grow. In one case, tree trunks are used, in the second, a loose substrate placed in plastic bags.
The first option is used outdoors, and the bags are placed in a basement, greenhouse or apartment. The best place is a deep, spacious cellar, with a stable temperature and humidity regime.
The nutrient substrate is divided into two types - on one, mycelium is grown, on the other, fruits are obtained. Plastic bags are filled with sawdust, wheat or barley straw, sunflower seed husk, crushed corn cobs, buckwheat husks, etc.
Wet, dead organics can quickly mold or rot when the temperature rises. In order to prevent these reactions, it is necessary to disinfect the premises and the substrate.
The material for growing mushrooms is thermally processed. The pot with straw, husk, sawdust is poured in such a way that on top of the substrate there is a layer of water of at least 20 cm. Boil for 2 hours, drain the water and dry the squeezed substrate. The smaller it is, the easier it is for mushrooms to grow.
A plastic bag is also disinfected. It is washed with a light solution of bleach or potassium permanganate a few days before the mycelium is colonized. The bag is filled with layers - 5 cm of substrate, 0.5 cm of mycelium, etc.
Small holes are cut in the tied bag every 10-15 cm.
Daylight hours for mushrooms should be 8 hours long. Sprouted parts of oyster mushrooms are regularly sprayed with water at a temperature of at least 20 degrees. The room now needs to be ventilated daily.
Fruits, ready to be harvested, appear one and a half weeks after the start of active growth of the mycelium. The mushrooms reach the desired size in 5 days. And the first crop is harvested within 30 days after the mycelium is settled in the bags. The yield of oyster mushrooms decreases as the substrate is depleted.
When growing outdoors, it is best to use freshly cut trees with a high moisture content. But the dry forest is kept in water for at least seven days. The tree is cut into blocks of 30-40 cm high.Thin trunks will give low yields, too thick blocks will slow down the growth of mycelium.
