Amanita virosa was originally described from Sweden and is known throughout Europe, with additional confirmed records from northern Asia (China). The name was formerly used for similar-looking agarics in North America, but research has shown that these American species, including the eastern Amanita bisporigera , the western A. ocreata , and ...
The destroying angel (Amanita bisporigera) and the death cap (Amanita phalloides) account for the overwhelming majority of deaths due to mushroom poisoning. The toxin responsible for this is amatoxin, which inhibits RNA polymerase II and III. Symptoms do not appear for 5 to 24 hours, by which time the toxins may already be absorbed and the ...
The genus Amanita was first published with its current meaning by Christian Hendrik Persoon in 1797. [1] Under the International Code of Botanical Nomenclature, Persoon's concept of Amanita, with Amanita muscaria (L.) Pers. as the type species, has been officially conserved against the older Amanita Boehm (1760), which is considered a synonym of Agaricus L. [2]
The following is a list of species of the agaric genus Amanita.This genus contains over 500 named species and varieties and follows the classification of subgenera and sections of Amanita outline by Corner and Bas; Bas, [1] [2] as used by Tulloss (2007) and modified by Redhead & al. (2016) [3] for Amanita subgenus Amanitina and Singer for Amanita section Roanokenses.
Amanita muscaria, commonly known as the fly agaric or fly amanita, [5] is a basidiomycete of the genus Amanita. It is a large white- gilled , white-spotted, and usually red mushroom. Despite its easily distinguishable features, A. muscaria is a fungus with several known variations, or subspecies .
Amanita phalloides is the type species of Amanita section Phalloideae, a group that contains all of the deadly poisonous Amanita species thus far identified. Most notable of these are the species known as destroying angels , namely A. virosa , A. bisporigera and A. ocreata , as well as the fool's mushroom ( A. verna ) .
The deadly A. ocreata and occasionally A. phalloides are found in the same habitat at the same time of year as A. velosa, and can often be found in close proximity. A. ocreata and A. phalloides have thin universal veil remnants, a sac-like volva, an annulus, a non-striate pileus margin, and a pileus that is a different color than A. velosa.
Amanita virosiformis, commonly known as the narrow-spored destroying angel, is a poisonous basidiomycete fungus, one of many in the genus Amanita. Originally described from Florida , it is found from coastal North Carolina through to eastern Texas in the southeastern United States.
