The Families of Mushrooms and Toadstools Represented in the British Isles


L. Watson and M. J. Dallwitz



Anamorphic forms occurring (these yeast-like).

Morphology. The fruit-bodies producing basidia and basidiospores. The basidia ‘modified’; retaining an apical tetrad of sessile basidiospores with no sterigmata. The basidiospores statismosporic.

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

Ecology. Parasitic, or saprophytic (presumably?); when parasitic, at least sometimes on other fungi. Marine (Cystofilobasidium includes some marine species), or non-marine.

British representation. 2 species in Britain; Cystofilobasidium.

World representation. 10 species; genera 3. “Widespread”.

Classification. Basidiomycota; Basidiomycetes; Tremellomycetidae; Cystofilobasidiales.
