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 (“gasteroid”); white or whitish (smooth to floccose). Gleba at first pale (buff). The basidia ‘unmodified’. The basidiospores sub-globose; hyaline to white; ornamented (warted).

The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer.

Ecology. Probably mycorrhizal (on grasses?). The fruit-bodies subterranean. Found in grassy places (being especially associated with grasses).

British representation. 1 species in Britain (G. simplex); Gastroporium.

World representation. 2 species; genera 1. Widespread in warm dry regions, especially Europe.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; dubiously Boletales (formerly ‘Hymenogastrales’).

Comments. Associated with Gramineae.
