The Families of Mushrooms and Toadstools Represented in the British Isles
Morphology. The fruit-bodies producing basidia and basidiospores; angiocarpic; a globose or tuberiform gasterocarp (with a prominent mycelial tuft below, the gleba olivaceous grey with radiating tramal plates, deliquescent); small; 1–1.5 cm across; white or whitish, or grey to blackish (subsequently). Gleba becoming mucilaginous and foetid. The peridium not dehiscent (not gelatinized). The basidia unmodified. The basidiospores statismosporic; smooth.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer.
Ecology. The fruit-bodies subterranean. Associated with broad-leaved trees. In calcareous soil at the bases of frondose trees. Found in broad-leaved woodland and in mixed woodland.
British representation. 4 species in Britain; Hysterangium.
World representation. 69 species; genera 11. Widespread, especially temperate.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Phallales.
