Pileus convex, expanding, often finally depressed, pigment variable, yellow, red, green, brown, black or unpigmented, smooth to tomentose, viscid to dry; pileal surface varied, often with an epicutis, subcutis and hypodermiallayers, pileocystidia and encrusted hyphae often present. Lamellae free to broadly adnate, occasionally subdecurrent, rather brittle, equal or with inter­mixed lamellulae, distant to crowded, thick to moderately thin, white to egg yellow. Stipe central, brittle, solid, hollow or stuffed, generally short and stout. VEIL mostly absent, very rarely with a persistent annulus.

Basidiospores from pure white to deep chrome or pinkish cream in mass, subglobose, obovoid or ellipsoid, hyaline, ornamented with eusporial verrucae and often with a more or less complete reticulum, coated with an amyloid myxosporium, with a more or less distinct amyloid suprahilar plage.
