‘Truffle’.
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).
Representation in Britain and Ireland. 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.
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.
