Template:FixBunching Amanita farinosa is a North American 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 or deciduous 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. roseotincta[1][2].
