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 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.
