The Families of Mushrooms and Toadstools Represented in the British Isles
Morphology. The fruit-bodies producing basidia and basidiospores; clustered, or solitary; angiocarpic; a globose or tuberiform gasterocarp (the gleba powdery); tiny to very large; 1–5 cm across, or 6–30 cm across; 1–30 cm high; white or whitish, or cream or yellowish, or straw-coloured, or light brown, or purplish brown, or dark brown, or grey, or blackish; with no particular odour other than an ordinary fungoid one. The gasterocarp with a columella. Capilliteum present. Gleba at first pale. The peridium dehiscent; opening via an apical pore, or opening irregularly (then by apical fragmentation and flaking away). The basidia unmodified; maturing simultaneously. The basidiospores statismosporic; brown; ornamented (obtusely verruculose).
The hyphae without clamp connections. 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; borne on the ground. Found in grassy places, in heathland, in broad-leaved woodland, in mixed woodland, in coniferous woodland, and in places modified by human activities.
British representation. Bovista, Bovistella, Calvatia, Handkea, Lycoperdon, Vascellum.
World representation. 158 species; genera 18. Widespread.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Agaricales.
Comments. Several Lycoperdon species edible (when young, L. giganteum being very good). White-fleshed puff-balls with an initially soft outer skin, which becomes papery at maturity and opens apically by bursting or via a pore.
