The Families of Mushrooms and Toadstools Represented in the British Isles
Morphology. The fruit-bodies producing basidia and basidiospores; persistent; attached laterally and bracket-shaped to fan-shaped (pleurotoid, with no more than a rudimentary stipe, the context tough and leathery); small to medium sized; in Schizophyllum commune, 1–4 cm across. The hymenium ostensibly borne on gills (with greyish-violet pseudo-lamellae). The gills atypical, rather obviously representing laterally flattened and radially elongated pores or cupules. The edges of the gills split longitudinally (each split half-revolute in dry conditions). Cystidia absent. The basidia unmodified. The basidiospores ballistosporic; hyaline; smooth; inamyloid.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer. The generative hyphae not inflated.
Ecology. Mainly saprophytic. The fruit-bodies on dead wood (mostly), or on living wood. Associated with broad-leaved trees. The fruit-bodies on dead trees and fallen logs and on stored and construction timber. On hardwoods: trunks and dead branches, also on newly felled wood and stacked timber. Found in broad-leaved woodland and in mixed woodland.
British representation. 9 species in Britain; Henningsomyces, Porotheleum, Rectipilus, Schizophyllum. Almost confined to southeast England.
World representation. 43 species; genera 5.
Classification. Basidiomycota; Basidiomycetes; Agaricomycetidae; Agaricales.
