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; persistent; angiocarpic; a globose or tuberiform gasterocarp (aporate, with a labyrinthoid chamber); brightly pigmented; brick- red, or orange (brick-red on the outside, and orange within). The basidia ‘unmodified’. The basidiospores with a peri-appendicular corona; statismosporic; cream; ornamented (verrucose); inamyloid.

The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The generative hyphae not inflated.

Ecology. The fruit-bodies subterranean, or subterranean to not subterranean (underground or half-exposed); when more or less epigeal, borne on the ground. Found in broad-leaved woodland, or in mixed woodland (usually under trees).

British representation. 1 species in Britain (S. caroticolor); Stephanospora.

World representation. 4 species; genera 1. “Widespread”.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Russulales (? - formerly Stereales).

Illustrations. • Stephanospora caroticola (Berkeley).
