‘Rust Fungi’.
Morphology. The fruit-bodies producing basidia and basidiospores; with flesh not beef-steak like (i.e., unlike that of Fistulina). The basidia ‘unmodified’.
The hyphal walls lamellate, with a thin, electron-dense outer layer and a relatively thick, electron-transparent inner layer.
Ecology. Parasitic; on vascular plants.
World representation. 4121 species (! - but few Rusts produce fruit-bodies regarded as “mushrooms” or “toadstools”); genera 17.
Classification. Basidiomycota; Urediniomycetes; Urediniomycetes ‘incertis sedis’.

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. See also Guidelines for using data taken from Web publications.
