L. Watson and M. J. Dallwitz

Leucogastraceae

Morphology. The fruit-bodies producing basidia and basidiospores; angiocarpic; a globose or tuberiform gasterocarp (the gleba with small locules and no real hymenium, mucilaginous at maturity and milky when cut); stinking foetid-foecal when mature. Gleba becoming mucilaginous and foetid. The basidia ‘unmodified’. The basidiospores thick walled; statismosporic; hyaline; ornamented (thick walled, with reticulato-alveolate ornamentation, and a gelatinous myxosporium); inamyloid.

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

Chemical reactions. Supposedly not yielding prenylated phenols and quinones.

British representation. 2 species in Britain; Leucogaster.

World representation. 25 species; genera 2. North temperate, widespread.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Boletales.

Comments. The gasterocarp loculate, the lacunose gleba compact.
