The Families of Mushrooms and Toadstools Represented in the British Isles
Morphology. The fruit-bodies producing basidia and basidiospores; ephemeral; angiocarpic; comprising a 1–2 cm. diameter head with a small, terminal pore, borne at ground level, atop a long, fibrillose, subterranean stipe (with apical dehiscence, the gleba compact, finally powdery); medium sized to large; with the head 1–2 cm across; 3–7 cm high (the stipe 2–5 cm). The basidia unmodified. The basidiospores statismosporic.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer.
Ecology. The fruit-bodies not subterranean (at least, with its spore-bearing upper component exposed). Found usually in sand dunes, but occasionally recorded from old walls.
British representation. Battarrea, Queletia, Schizostoma, Tulostoma.
World representation. 87 species; genera 6. Widespread, but mainly in dry regions.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Agaricales.
Comments. The basidium pleurosporous.
