The Families of Mushrooms and Toadstools Represented in the British Isles


L. Watson and M. J. Dallwitz


~ Stereaceae.

Morphology. The fruit-bodies producing basidia and basidiospores; persistent; flattened and more or less appressed to the substrate or encrusting, with the hymenium on the outside; medium sized to large. The upper surface cream or yellowish to straw-coloured, or yellowish-brown to reddish-brown, or blackish (or blueish tinged). The hymenium smooth, or irregularly folded, ridged or wrinkled. The hymenial layer not readily separable from the supporting flesh. Cystidia present; gloeocystidia (or metuloids). The basidia ‘unmodified’; not of the ceratobasidialean type (q.v.). The basidiospores ballistosporic; hyaline to white, or pink; smooth; inamyloid.

The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The hyphae monomitic. The generative hyphae not inflated.

Chemical reactions. The context hyphae not xanthochroic.

Ecology. Saprophytic, or parasitic and saprophytic. The fruit-bodies only on dead wood (?), or on dead wood and on living wood (?). Associated with conifers (Abies). The fruit-bodies on dead trees and fallen logs, or on trunks and branches of living trees and on dead trees and fallen logs (?).

British representation. 1 species in Britain; Veluticeps abietina.

World representation. 15 species; genera 4. North temperate, widespread.

Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Polyporales.
