Ubiquitous, the most common, "standard-issue" funnel-cap — it can be encountered throughout almost the entire mushroom season in a wide variety of places: in urban parks, in light birch forests, and in dense dark coniferous woods. The combination of its funnel-shaped form, pale pink or beige cap color, relatively slender habit, and characteristic odor with a hint of bitter almond makes it one of the most easily recognizable species of this difficult genus.
The odor of the Funnel Funnel-cap is due to a relatively high, though safe for humans, content of hydrocyanic acid, i.e., cyanide — possibly, this is how the mushroom defends itself against insects (springtails and fly larvae). Incidentally, the Fairy Ring Mushroom (Marasmius oreades), known for its sharp, fragrant smell, also releases cyanide.
2–10 cm in diameter, initially convex with an incurved margin, then spreading and funnel-shaped with a wavy, uneven margin. The surface is smooth, non-hygrophanous, flesh-colored, ochre, less often pinkish.
Gills decurrent, whitish to beige, occasionally forked.
2.5–5 cm long, 0.5–1 cm in diameter, central, cylindrical, concolorous with the cap or slightly lighter, smooth, with a felt-like pubescence at the base.
Thin, white, fibrous.
Almond-like, weak.
Spore print white. Spores elliptical in shape, smooth, transparent.
A litter saprotroph. Grows singly and in groups in deciduous, mixed, coniferous, and dark coniferous forests, among grass and mosses. The mushroom is widely distributed in the temperate zone of the Northern Hemisphere.
Funnel-cap with bent margin (Infundibulicybe geotropa) — significantly larger in size.
Red-ochre Bonomyces (Bonomyces sinopicus) — gills and flesh with a waxy-yellow tint, cap brick-red with fine cracks.
