''Clitocybe'' is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus. ''Clitocybe'' means ''sloping head''. A few members of the genus are considered edible; many others are poisonous, containing the toxin muscarine among others. Distinguishing individual species of ''Clitocybe'' is generally prohibitively difficult to non-experts, requiring the analysis of microscopic characters. Therefore, with the exception of a few charismatic and readily identified members, ''Clitocybe'' mushrooms are rarely collected for consumption. ==Taxonomy== ''Clitocybe'' was originally proposed by Elias Fries in 1821 as a tribe in the genus ''Agaricus''. Friedrich Staude elevated it to generic status in 1857. Recent molecular work has shown the genus to be polyphyletic, with many members seemingly distantly related and other fungi, such as the field blewit and wood blewit, now known as ''Clitocybe saeva'' and ''C. nuda'' respectively, are more closely related. As ''C. nebularis'' is the type species,〔 those most distantly related to it would be likely to be reclassified in the future. In a 2003 paper, Finnish mycologist Harri Harmaja proposed ''C. geotropa'' and twelve other ''Clitocybe'' species be split off into a new genus ''Infundibulicybe'' on the basis of spore properties. He also reclassified ''C. clavipes'' in the genus ''Ampulloclitocybe'', that genus name taking precedence over his own proposal ''Clavicybe''.〔 Other former ''Clitocybe'' species have been placed in the genera ''Atractosporocybe'', ''Leucocybe'' and ''Rhizocybe''.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Clitocybe」の詳細全文を読む スポンサード リンク
