The Families of Mushrooms and Toadstools Represented in the British Isles


L. Watson and M. J. Dallwitz


Morphology. The fruit-bodies producing basidia and basidiospores; pustulate (to tuberculate); gelatinous and somewhat translucent when moist. The basidia ‘modified’ (individually, and often catenulate (in chains), with deciduous sterigmata); cruciately divided. The basidiospores ballistosporic.

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

Ecology. Saprophytic. The fruit-bodies on dead wood.

British representation. 3 species in Britain; Sirobasidium, Xenolachne.

World representation. 11 species; genera 3. Widespread, especially tropical.

Classification. Basidiomycota; Basidiomycetes; Tremellomycetidae; Tremellales.
