The Genus Crepidotus [ Basidiomycetes > Agaricales > Crepidotaceae . . . ] by Michael Kuo This genus of small, brown-spored pleurotoid mushrooms contains a multitude of boring whitish to brownish species and a few (well, two) that are more interesting. The rare Crepidotus cinnabarinus is bright red, and Crepidotus crocophyllus usually features yellow to orange gills . . . but everything else is brown or white, and requires extensive microscopic study for accurate identification. Microscopic features used to separate species in Crepidotus include the anatomy of spores, cheilocystidia, and pileipellis, as well as determining the presence or absence of clamp connections. Hesler & Smith's 1965 monograph of the genus in North America is the starting place for identification work, but Mexican researchers Victor Bandala and Leticia Montoya have made substantial contributions to North American Crepidotus research in a series of recent publications (2000a, 2000b, 2008a, 2008b)--and they have simplified the picture somewhat by widening species concepts and allowing for more variability in features.
