Clustered domecap or Lyophyllum immundum

Cap 3-7 cm across, hemispherical to convex in young mushrooms, becoming flat and spread out with a small bump in the center with age. Color: gray-brown, mousy brown, earthy gray — muted, with no bright tones. The surface is silky-matte and smooth; in wet weather it is slightly darker.

Cap 4–12 cm, hemispherical in young mushrooms, then flattening to plano-convex, almost flat in old ones, with a slightly raised center. The color varies: grayish, brownish, ochre, sometimes almost white or chocolate. The surface is smooth, dry, slightly sticky in wet weather. The skin does not peel.

The hymenophore is made of gills. The gills are crowded, thin, notched where they meet the stem. Color whitish to grayish, becoming cream-ocher with age. Spore print white.

Gills attached to the stem or slightly decurrent. White when young, turning yellowish with age, cream with an ochre tint in mature mushrooms. Crowded. Spore print white.

Stem 4-7 cm tall, 0.5-1.2 cm thick, cylindrical, slightly thickened in the lower part. Color whitish to cream, with white mycelial down at the base. The surface is lengthwise fibrous, with no ring.

Stem 5–10 cm tall, 1–3 cm thick, cylindrical, sometimes somewhat curved because of the clustered growth. Whitish gray, with no ring and no volva. At the base it is often fused with others in the cluster, forming a shared "heel".

The flesh is thin, whitish to grayish, soft. It does not change color when cut. No pronounced smell.

Flesh white, springy in young mushrooms, becoming cottony and moist with age. Does NOT change color when cut. The texture is slightly cartilaginous in the stem, more tender in the cap.

Faint, neutral, mushroomy, not distinctive. Do not taste it — its safety status is undetermined.

Smell faint, mushroomy, without distinctive notes. Taste mild, bland and neutral. Some specimens have a barely noticeable sweetish note.
