| The families of mushrooms and toadstools represented in Britain and Ireland |
Formerly in Ceratobasidiaceae
Anamorphic forms occurring (Oliveorhiza).
Morphology. The fruit-bodies producing basidia and basidiospores; flattened and more or less appressed to the substrate or encrusting, with the hymenium on the outside (thin, waxy, resupinate). The basidia ‘unmodified’; of characteristic form, being pyriform with very stout sterigmata (with long, stout sterigmata, probasidium absent); maturing at different times. The basidiospores ballistosporic; inamyloid.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer.
Chemical reactions. The context hyphae not xanthochroic (?).
Representation in Britain and Ireland. 4 species in Britain; Oliveonia.
World representation. 4 species, or 5 species; genera 2 (?). “Widespread”.
Classification. Basidiomycota; Basidiomycetes; Tremellomycetidae; Ceratobasidiales.
Comments. This inadequate description lacks the informaton to justify the recent removal of Oliveonia from Ceratobasidiaceae, involving its transfer from Agaricomycetidae to Tremellales.
We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa.
