The Families of Mushrooms and Toadstools Represented in the British Isles


L. Watson and M. J. Dallwitz


Formerly Coriolaceae.

Morphology. The fruit-bodies producing basidia and basidiospores; persistent; leathery, attached laterally and bracket-shaped; small to medium sized; in Bjerkandera adusta, 2–4 cm across. The hymenium porose. The hymenial layer not readily separable from the supporting flesh. The basidia ‘unmodified’. The basidiospores ballistosporic; hyaline.

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.

Chemical reactions. The context hyphae not xanthochroic.

Ecology. Saprophytic, or parasitic and saprophytic. The fruit-bodies on dead wood and on living wood. Associated with broad-leaved trees and with conifers (?). The fruit-bodies on trunks and branches of living trees and on dead trees and fallen logs. On trunks of various tree species. Found in coniferous woodland (?), or in broad-leaved woodland and in mixed woodland.

British representation. 25 species in Britain; Aurantiporus, Bjerkandera, Ceriporia, Ceriporiopsis, Climacocystis, Hapalopilus, Ischnoderma, Leptoporus, Spongipellis.

World representation. 78 species; genera 10. “Widespread”.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Polyporales.
