Hygrocybe conica

A species with a conical cap that blackens with development, pressure, or bruising.

Suprapellis composed of a thin layer of hyaline hyphae arranged parallelly, up to only 4 µm wide, very slightly separated by gelification, with dark grey intracellular pigment that blackens with age; beneath these lie hyphae with yellowish intracellular pigment, 7-10 µm wide, in both layers with simple septa (clampless).

Gill edge fertile, without differentiated elements from the basidia.

Basidia clavate, 35-50 µm long and 8-9 µm wide, without basal clamps, 2-spored.

Spores ellipsoidal, smooth, hyaline, thin-walled, with a lateral apiculus at one end, one or more oil droplets inside, inamyloid in Melzer's reagent.
