L. Watson and M.J. Dallwitz

Hapalopilaceae

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 (?), in broad-leaved woodland and in mixed woodland.

Representation in Britain and Ireland. 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.

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.
