''Amanita onusta'', commonly known as the loaded Lepidella or the gunpowder Lepidella, is a species of fungus in the Amanitaceae family of mushrooms. It is characterized by its small to medium-sized fruit bodies that have white to pale gray caps crowded with roughly conical, pyramidal, or irregular gray warts. The stipe is whitish-gray with woolly or wart-like veil remnants, and at the base is a spindle- or turnip-shaped base that is rooted somewhat deeply in the soil. The species is distributed in eastern North America, from Nova Scotia to Mexico, and may be found growing on the ground in deciduous forests, particularly those with oak, hickory and chestnut. Fruit bodies smell somewhat like bleaching powder, and their edibility is unknown, but possibly toxic. ==Taxonomy== ''Amanita onusta'' was first described in 1874 by American mycologist Elliot Calvin Howe as ''Agaricus onustus''.〔 Later, in 1891, Pier Andrea Saccardo transferred the species to the genus ''Amanita''.〔 ''Amanita'' authority Cornelis Bas, writing in his extensive 1969 monograph on the genus,〔 placed the species in his stirps ''Microlepis'', subsection ''Solitariae'', section ''Lepidellus''.〔 This grouping of ''Amanita'' mushroom species also includes ''A. abrupta'', ''A. atkinsoniana'', ''A. costaricensis'' (a provisionally named species authored by Tulloss, Halling, & G.M. Muell.), ''A. nitida'' (as Coker〔 described the species) and ''A. sphaerobulbosa''.〔 The Latin epithet ''onustusa'' means "charged, load-carrying, burdened",〔〔 and a regular adjective derived from ''onus'', "burden"〔 (the same word that gave the English ''onus'').〔 ''A. onusta'' is commonly known as the "loaded Lepidella",〔 or the "gunpowder Lepidella".〔
