🔬 Morphology

Cap

Poisonpie

Cap 4-10 cm, hemispherical at first, then flat-convex with a broad umbo. Color sandy yellow to creamy brown, darker in the center. Surface sticky (hence the Ukrainian name, “sticky hebeloma”) — distinctly slimy in wet weather, glossy in dry weather, as if varnished.

Clustered domecap

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.

Hymenophore

Poisonpie

Gilled hymenophore. Gills crowded, notched-adnate to the stem. White at first, turning reddish brown with age from the color of the spores. Young mushrooms form distinctive “droplets” of moisture on the gills — a diagnostic feature of the genus Hebeloma. Spore print rusty brown.

Clustered domecap

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

Poisonpie

Stem 3-10 cm tall, 1-1.5 cm thick, often with a club-shaped, thickened base. Color white, yellowing with age, especially near the bottom. Surface covered with a fine white mealy bloom. No ring.

Clustered domecap

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".

Flesh

Poisonpie

The flesh is white or creamy, yellowing slightly in old mushrooms. Doesn't change color when cut. Texture firm but not springy.

Clustered domecap

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.

Smell

Poisonpie

distinct radish smell — the key diagnostic feature. Some authors describe it as “rotting radish.” Taste bitterish, unpleasant. Don't taste it raw — it's mildly toxic.

Clustered domecap

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