The Families of Mushrooms and Toadstools Represented in the British Isles
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 or effuso-reflexed, often encrusted). The hymenium smooth, or irregularly folded, ridged or wrinkled (with no hyphal pegs). The hymenial layer not readily separable from the supporting flesh. Cystidia present; skeletocystidia. The basidia unmodified; not of the ceratobasidialean type (q.v.). The basidiospores ballistosporic; hyaline; smooth; inamyloid.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The hyphae dimitic (with skeletal hyphae). The generative hyphae not inflated.
Chemical reactions. The context hyphae not xanthochroic.
Ecology. Parasitic, or saprophytic.
British representation. 23 species in Britain; Antrodiella, Diplomitoporus, Flaviporus, Junghuhnia, Mycoleptodon, Odontia, Steccherinum.
World representation. 106 species; genera 14. Widespread.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Polyporales (formerly Stereales).
