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 .
Amavadin is a vanadium-containing anion found in three species of poisonous Amanita mushrooms: A. muscaria, A. regalis, and A. velatipes. [1] Amavadin was first isolated and identified in 1972 by Kneifel and Bayer. [2] This anion, which appears as a blue solution, is an eight-coordinate vanadium complex. [1]
Amanita muscaria is edible if parboiled to leach out toxins; [19] fresh mushrooms cause vomiting, twitching, drowsiness, and hallucinations due to the presence of muscimol. Although present in A. muscaria, ibotenic acid is not in high enough concentration to produce any physical or psychological effects unless massive amounts are ingested.
The fly agaric, Amanita muscaria, late August, Norway An agaric (/ ˈ æ ɡ ər ɪ k, ə ˈ ɡ ær ɪ k /) is a type of fungal fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus.
Amanita muscaria var. formosa, known as the yellow orange fly agaric, is a hallucinogenic and poisonous [1] basidiomycete fungus of the genus Amanita.This variety, which can sometimes be distinguished from most other A. muscaria by its yellow cap, is a European taxon, although several North American field guides have referred A. muscaria var. guessowii to this name. [2]
The stipe is 1–3 cm, more or less equal or narrowing upwards and slightly flaring at the apex. It is white to yellowish cream, densely stuffed with a pith, the skirt-like ring is membranous, persistent, the lower stipe and upper bulb are decorated with partial or complete concentric rings of volval material that are bright pale yellow to cream or sordid cream.
Chalciporus piperatus, commonly known as the peppery bolete, is a small pored mushroom of the family Boletaceae found in mixed woodland in Europe and North America. It has been recorded under introduced trees in Brazil, and has become naturalised in Tasmania and spread under native Nothofagus cunninghamii trees.
Amanita muscaria. Muscarine, L-(+)-muscarine, or muscarin is a natural product found in certain mushrooms, particularly in Inocybe and Clitocybe species, such as the deadly C. dealbata. Mushrooms in the genera Entoloma and Mycena have also been found to contain levels of muscarine which can be dangerous if ingested.
