Row crowded

Crowded lyophyllum is very widespread. Until recently, it was believed that the main "patrimony" 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, as of today (2018), L. fumosum species has been abolished, and is considered a synonym for L.decastes,significantly expanding the habitat of the latter, practically 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 fruit bodies with thicker legs, growth in small aggregates or separately, binding to dry pine forests, and at the molecular level.growth in small aggregates or separately, tied to dry pine forests, well, at the molecular level.growth in small aggregates or separately, tied to dry pine forests, well, at the molecular level.



The crowded row has a large cap, 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.) ). 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, elastic, with a weak "ordinary" smell.


Relatively frequent, white, loose or loose.

Spore powder:



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. Color - from white to brownish (especially in the lower part), smooth surface, fibrous pulp, 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, in meadows, in forbs. In most cases, it bears fruit in large aggregates.

Similar species

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.
