Crowded lyophyllum is very widespread. Until recently, it was believed that the main 'fiefdom' of this mushroom is parks, squares, roadsides, slopes, edges and similar open and semi-open places. At the same time, there was a separate species, Lyophyllum fumosum (L. smoky-gray), associated with forests, especially conifers, some sources even described it as a mycorrhizal forming agent with pine or spruce, outwardly very similar to L.decastes and L.shimeji. Recent molecular studies have shown that no such separate species exists, and all finds classified as L. fumosum are either L.decastes (more commonly) or L. shimeji (less commonly pine forests). Thus, today (2018), the species L.fumosum has been abolished, and is considered synonymous with L.decastes, significantly expanding the habitat of the latter, almost to 'anywhere'. Well, L.shimeji, as it turned out, grows not only in Japan and the Far East, but is widespread throughout the boreal zone from Scandinavia to Japan, and, in some places, is found in pine forests of the temperate climatic zone. It differs from L.decastes only in larger fruiting bodies with thicker legs, growth in small aggregates or separately, binding to dry pine forests, and at the molecular level.
Hat: A crowded row has a large hat, 4-10 cm in diameter, in youth it is hemispherical, cushion-shaped, as the mushroom matures, it opens to half-spread, less often spread, often losing the geometric correctness of the outlines (the edge turns upward, becomes wavy, cracks, etc.). P.). Caps of different sizes and shapes can usually be found in one splice. The color is gray-brown, the surface is smooth, often with adhered earth. The flesh of the cap is thick, white, dense, firm, with a slight 'ordinary' odor.
Blades: Relatively frequent, white, poorly adherent or loose.
Spore powder: White.
Leg: Thickness 0.5-1.5 cm, height 5-10 cm, cylindrical, often with a thickened lower part, often twisted, deformed, fused with the base with other legs. The color is from white to brownish (especially in the lower part), the surface is smooth, the pulp is fibrous, very strong.
Late mushroom; occurs from late August to late October in forests of various types, preferring specific areas such as forest roads, thinned edges; sometimes comes across in parks, meadows, in forbs. In most cases, it bears fruit in large aggregates.
The fused row (Lyophyllum connatum) has a light color. The crowded row can be confused with some edible and inedible species of lamellar mushrooms, growing concretions. Among them are mentioned such species of the family as Collybia acervata (a smaller mushroom with a reddish tinge of the cap and stem), and Hypsizygus tessulatus, which causes brown wood rot, as well as some species of honey agarics from the genus Armillariella and meadow honey (Marasmius oreades).
The crowded row is considered a low-quality edible mushroom; the texture of the pulp gives a comprehensive answer why.
