The Families of Mushrooms and Toadstools Represented in the British Isles
Morphology. The fruit-bodies producing basidia and basidiospores; persistent; clustered; attached laterally and bracket-shaped (somewhat stipitate, corky, the brown cap zoned, the flesh also brown); medium sized to large; 3–6 cm across; dark reddish-brown, or dark brown. The hymenium ostensibly borne on gills (these very irregularly forked and interrupted, e.g. in G. sepiarium), or ribbed. The gills in such as G. sepiarium atypical, rather obviously representing laterally flattened and radially elongated pores or cupules. The edges of the gills not split longitudinally. The hymenial layer not readily separable from the supporting flesh. Cystidia present, or absent (absent from G. sepiarium). The basidia unmodified. The basidiospores cylindric, in G. sepiarium white and slightly curved; hyaline, or white.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The hyphae dimitic. The generative hyphae not inflated.
Ecology. Saprophytic. The fruit-bodies on dead wood; on dead trees and fallen logs and on stored and construction timber (G. sepiarium causing serious decay of coniferous timber in the open, rarely also in houses).
British representation. 4 species in Britain; Gloeophyllum.
World representation. 9 species; genera 1. Widespread.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Polyporales.
