'''''Lepiota''''' is a [[genus]] of gilled [[mushroom]]s, in the order [[Agaricales]]. Though they have white spores, they are related to the familiar brown spored mushrooms of the genus ''[[Agaricus]]''. They typically have rings on the stems, which in larger species are detachable and glide up and down the stem. The cap usually has scales: the colours of the cap, gills and scales are important in determining the exact species, as is sometimes the smell.
The term is likely derived from the [[Ancient Greek|Greek]] λεπις, "scale". The basionym is ''Agaricus'' sect. ''Lepiota'' [[Christian Hendrik Persoon|Pers.]] 1797, devalidated by later starting date, so the citation is (Pers.) ''per'' S.F.Gray. It was only described, without species, and covered an earlier mentioned, but unnamed group of ringed, non-volvate species, regardless of spore color. The Swedish mycologist [[Elias Magnus Fries]] restricted the genus to white-spored species, and made into a tribe, which was, like ''[[Amanita]]'', repeatedly raised to genus rank.<ref name = "Donk62">{{cite journal| last=Donk| first=M.A.| title=The generic names proposed for Agaricaceae| journal=Beiheifte zur Nova Hedwigia| pages=1–320| volume=5| year=1962| issn= 0078-2238}}</ref>
The type species is unclear. ''[[Macrolepiota procera|L. procera]]'' is considered the type by Earle in 1909. ''Agaricus columbrinus'' (''[[Lepiota clypeolaria|L. clypeolaria]]'') was also suggested (by Singer, 1946) to avoid the many combination involved otherwise in splitting ''[[Macrolepiota]]'', which include ''L. procera''. Since both species had been placed into different genera prior to their selection (in ''[[Leucocoprinus]]'' and ''Mastocephalus'' respectively), Donk observes that a conservation will probably be needed, expressing support for Singer's emendation.<ref name = "Donk62"/>
With respect to [[mushroom hunting|mushrooming]], this is a genus to be avoided as several species contain [[amanitins]] and are highly toxic.<ref name ="Bnejamin95">Benjamin DR. (1995).

Previously, the most familiar species were the larger species, such as the [[parasol mushroom]] and the [[shaggy parasol]]. However, these have now been placed in the different genera ''[[Macrolepiota]]'' and ''[[Chlorophyllum]]''. However the status of the genera is not unanimous as some current books still leave the members of ''Macrolepiota'' in ''Lepiota''.<ref name = "Phillips91">{{cite book | author = Phillips R | year = 1991 | title = Mushrooms of North America | publisher = Little, Brown & Co. | id = ISBN}}</ref>
