Formerly Corticiaceae p.p.
Morphology. The fruit-bodies producing basidia and basidiospores; persistent; flattened and more or less appressed to the substrate or encrusting, with the hymenium on the outside (resupinate, waxy); white or whitish. The hymenium with pegs or spinose, or smooth. The hymenial layer not readily separable from the supporting flesh. The hymenium not thickening. Cystidia (hymenial) present; gloeocystidia. Hyphidia represented by dendrohyphidia. The basidia ‘unmodified’; not of the ceratobasidialean type (q.v.). The basidiospores white; smooth; inamyloid.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The hyphae dimitic.
Ecology. Parasitic, or saprophytic. The fruit-bodies borne on the ground, or on dead wood, or on living wood (lignicolous, herbicolous or humicolous).
British representation. About 5 species in Britain; Crustomyces, Parvobasidium.
World representation. 26 species; genera 8. “Widespread”.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Polyporales.
