howEdible=poisonous"Amanita farinosa" is a
North America n poisonous mushroom of the genus "Amanita ", a genus of fungi including some of the most deadly mushrooms, as well as notably psychedelic mushrooms.Description
The cap is 2.5-7 cm (1-2.8 inches) in diameter, domed in young and flat in older specimens, with a striate margin. It is whitish grey and covered with brownish grey volval material. The gills are white , as is the stipe (stem). The stem, up to 6.5 cm high, lacks a ring, and at its base a smallish bulb or volva.
Distribution and habitat
An uncommon mushroom, it is found across North America in late summer to late autumn in
coniferous ordeciduous woodlands.Classification
Two recent molecular studies show that "Amanita farinosa" is part of a subgroup within "
Amanita " with its close relatives the Fly Agaric ("Amanita muscaria "), "A. gemmata" and "A. roseitincta" [Moncalvo J-M, Drehmel D, & Vilgalys R. (2000). Variation in modes and rates of evolution in nuclear and mitochondrial ribosomal DNA in the mushroom genus "Amanita" (Agaricales, Basidiomycota): phylogenetic implications. "Molecular Phylogenetic and Evolution" 16:48-63. ] [Drehmel D, Moncalvo J-M, & Vilgalys R. (1999).
