 with various deciduous and coniferous trees. The quintessential toadstool, it is a large white-gilled, white-spotted, usually deep red mushroom, one of the most recognizable and widely encountered in popular culture. Several subspecies, with differing cap colour have been recognised to date, including the brown regalis (considered a separate species), the yellow-orange flavivolata, guessowii, and formosa, and the pinkish persicina. Genetic studies published in 2006 and 2008 show several sharply delineated clades which may represent separate species.

Although generally considered poisonous, deaths are extremely rare, and it has been consumed as a food in parts of Europe, Asia, and North America after parboiling in plentiful water.

Specimens belonging to all three clades have been found in Alaska; this has led to the hypothesis that this was the center of diversification of this species. The study also looked at four named varieties of this species: var. alba, var. flavivolvata, var. formosa (including var. guessowii), and var. regalis from both areas. All four varieties were found within both the Eurasian and North American clades, evidence that these morphological forms are simply polymorphisms

s in all stages of development.
Fly agaric fruiting bodies emerge from the soil looking like a white egg, covered in the white warty material of the universal veil. Dissecting the mushroom at this stage will reveal a characteristic yellowish layer of skin under the veil which assists in identification. As the fungus grows, the red color appears through the broken veil and the warts become less prominent; they do not change in size but are reduced relative to the expanding skin area. The cap changes from globose to hemispherical, and finally to plate-like and flat in mature specimens. Fully grown, the bright red cap

Amanita caesarea can be distinguished as it has an entire orange red cap, lacking the numerous white warty spots of the fly agaric. Furthermore the stem, gills and ring are bright yellow, not white. Finally the volva is a distinct white bag, not broken into scales. In Australia, the introduced fly agaric may be confused with the native vermilion grisette (Amanita xanthocephala

, are known to be psychoactive. A toxic dose in adults is approximately 6 mg muscimol or 30 to 60 mg ibotenic acid, this is typically about the amount found in one cap of Amanita muscaria. However, the amount and ratio of chemical compounds per mushroom varies widely from region to region and season to season, which further confuses the issue. Spring and summer mushrooms have been reported to contain up to 10 times as much ibotenic acid and muscimol compared to autumn fruitings.

A fatal dose has been calculated at approximately 15 caps. Deaths from A. muscaria have been reported in historical journal articles and newspaper reports; however, with modern medical treatment a fatal outcome would be extremely rare. Many older books mistakenly list it as deadly, giving the impression that it is far more toxic than it really is. The North American Mycological Association has stated there are no reliably documented fatalities in the past 100 years. The vast majority (90% or more) of mushroom poisoning

The active constituents of this species are water soluble, and boiling and then discarding the cooking water will at least partly detoxify A. muscaria. However, drying may increase potency as the process facilitates the conversion of ibotenic acid to the more potent muscimol. According to some sources, once detoxified, the mushroom becomes edible.

 (usually by drying) of ibotenic acid. Muscimol and ibotenic acid were discovered in the mid 20th century. Researchers in England, Japan, and Switzerland showed that the effects produced were due mainly to ibotenic acid and muscimol, not muscarine. They are not distributed uniformly in the mushroom. Most are detected in the cap of the fruit, than in the base,with the smallest amount in the stalk.(Lampe, 1978; Tsunoda et al., 1993) A substantial fraction of ingested ibotenic acid is excreted in the urine unmetabolized quite rapidly, between 20 and 90 minutes after ingestion.. Virtually no muscimol is excreted when pure ibotenic acid is eaten, but muscimol is detectable in the urine after eating A. muscaria, which contains both ibotenic acid and muscimol.

, which received widespread publicity and popular support at the time. He noted that descriptions of Soma omitted description of roots, stems or seeds, which suggested a mushroom, and used the adjective hári "dazzling" or "flaming" which the author interprets as red. One line described men urinating Soma; this recalled the practice of recycling urine in Siberia. Soma is mentioned as coming "from the mountains", which Wasson interpreted as being brought with the Aryan invaders from the north. However, Indian scholars Santosh Kumar Dash and Sachinanda Padhy noted that both the eating of mushrooms and drinking of urine were proscribed, using as a source the Manusmṛti.
In 1971, Vedic scholar John Brough from Cambridge University rejected Wasson's theory; he noted the language was too vague to determine a description of Soma.

The notion has become widespread since the 19th century, but no contemporary sources mention this use or anything similar in their description of berserkers.
Today, it is generally considered an urban legend or at best speculation that cannot be proven. Muscimol is generally a mild relaxant, but could create a range of reactions within a range of people. It is possible that it could make a person incredibly angry, as well as make them "very jolly or sad, jump about, dance, sing or give way to great fright".

He concludes that if the theory was true, the use of the mushroom must have been "the best kept secret in the world" as it was so well concealed for all this time.

Culinary use


The toxins in A. muscaria are water soluble. When sliced thinly, or chopped into thin dice and boiled in plentiful water until thoroughly cooked, it seems to be detoxified. Although its consumption as a food has never been widespread, the consumption of detoxified A. muscaria has been practiced in some localities in Europe (notably by Russian settlers in Siberia) since at least the 19th century, and likely earlier. The German physician and naturalist Georg Heinrich von Langsdorff wrote the earliest published account on how to detoxify this mushroom in 1823. In the late 19th Century, the French physician Félix Archimède Pouchet

 was a popularizer and advocate of A. muscaria consumption, comparing it to manioc, an important food source in tropical South America that nevertheless must be detoxified before consumption.

Use of this mushroom as a food source also seems to have existed in North America as well. A classic description of this use of A. muscaria by an African-American mushroom seller in Washington D.C. in the late nineteenth century is described by American botanist Frederick Vernon Coville
