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; angiocarpic; a globose or tuberiform gasterocarp (an epigeal gasterocarp, with homogeneous gleba, dehiscing via irregular lobes from the apex); with no particular odour other than an ordinary fungoid one. The gasterocarp without a columella. Capilliteum present. Gleba at first pale. The peridium dehiscent. The basidia ‘unmodified’. The basidiospores statismosporic; white, or rusty brown, or brown, or fuscous (? - not hyaline); ornamented (reticulate, large).

The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. Spaerocysts not occurring among the context hyphae.

Ecology. Saprophytic, or mycorrhizal (?). The fruit-bodies not subterranean; borne on the ground.

British representation. 1 species in Britain (M. corium); Mycenastrum.

World representation. 1 species; genera 1. Widespread.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Agaricales.
