The Families of Mushrooms and Toadstools Represented in the British Isles


L. Watson and M. J. Dallwitz


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; pale, white or whitish, or grey. The hymenium with pegs or spinose (odontoid, with hyphal pegs). The hymenial layer not readily separable from the supporting flesh. Cystidia present, or absent (? - but skeletocystidia absent, unlike Steccherinaceae). Hyphidia represented by dendrohyphidia. The basidia ‘unmodified’; not of the ceratobasidialean type (q.v.). The basidiospores very large, fusiform; ballistosporic; hyaline; inamyloid.

The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The hyphae dimitic. The generative hyphae not inflated.

Ecology. Parasitic, or saprophytic; on vascular plants. Specialising in monocots.

British representation. 1 species in Britain (E. typhae); Epithele.

World representation. 13 species; genera 3. “Widespread”.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Polyporales (formerly Stereales).

Illustrations. • Epithele typhae (Petersens).
