| The families of mushrooms and toadstools represented in Britain and Ireland |
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.
Representation in Britain and Ireland. 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).
We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
