A '''légyölő galóca''' (''Amanita muscaria'') is a [[basidiomycete]] of the genus ''[[Amanita]]''. It is also a [[muscimol mushroom]]. Native throughout the [[temperate]] and [[boreal ecosystem|boreal]] regions of the Northern Hemisphere, ''Amanita muscaria'' has been unintentionally [[introduced species|introduced]] to many countries in the Southern Hemisphere, generally as a [[symbiont]] with pine and birch plantations, and is now a true [[Cosmopolitan distribution|cosmopolitan]] species. It [[mycorrhiza|associates]] with various [[deciduous]] and [[coniferous]] trees.
Arguably the most iconic [[toadstool]] species, the fly agaric is a large white-[[lamella (mycology)|gilled]], white-spotted, usually red mushroom, and is one of the most recognizable and widely encountered in popular culture. This includes video game design, such as the extensive use of a recognizable ''Amantia muscaria'' in the [[Mario_(franchise)|Mario]] franchise and its [[Super_Mario#Mushrooms|Super Mushroom]] power up.<ref>https://www.sciencedirect.com/science/article/abs/pii/S0024320505008805</ref>
Despite its easily distinguishable features, ''Amanita muscaria'' is a fungus with several known variations, or subspecies. These subspecies are slightly different, some have yellow or white caps, but they are all usually called fly agarics, and they are most of the time recognizable by their notable white spots. Recent DNA fungi research, however, has shown that some of these variations are not muscarias at all, such as the [[peach-colored fly agaric]] for example, but the common name 'fly agaric' clings on.
Although classified as [[poisonous mushroom|poisonous]], reports of human deaths resulting from ''A. muscaria'' ingestion are extremely rare. After [[parboiling]] twice with water draining—which weakens its toxicity and breaks down the mushroom's psychoactive substances—it is eaten in parts of Europe, Asia, and North America. All ''Amanita muscaria'' varieties, but in particular ''A. muscaria var. muscaria'', are noted for their [[hallucinogenic]] properties, with the main psychoactive constituents being the neurotoxins [[ibotenic acid]] and [[muscimol]]. A local variety of the mushroom was used as an intoxicant and [[entheogen]] by the indigenous [[peoples of Siberia]] and by the [[Sámi]], and has a religious significance in these cultures. There has been much speculation on possible traditional use of this mushroom as an intoxicant in other places such as the Middle East, Eurasia, North America, and Scandinavia.
==Description==
[[File:Amanita muscaria section 1 WF orig.jpg|thumb|right|Cross section of fruiting body, showing pigment under skin and free gills|alt=A white-fleshed mushroom with a red skin cut in half]]
A large, conspicuous [[mushroom]], ''Amanita muscaria'' is generally common and numerous where it grows, and is often found in groups with [[basidiocarp]]s in all stages of development.
Fly agaric fruiting bodies emerge from the soil looking like white eggs. After emerging from the ground, the cap is covered with numerous small white to yellow pyramid-shaped warts. These are remnants of the [[universal veil]], a membrane that encloses the entire mushroom when it is still very young. Dissecting the mushroom at this stage reveals a characteristic yellowish layer of skin under the veil, which helps identification. As the fungus grows, the red colour 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 [[wikt:globose|globose]] to hemispherical, and finally to plate-like and flat in mature specimens.<ref>{{cite book|author=Zeitlmayr L.|year=1976|title=Wild mushrooms: an illustrated handbook|publisher=Hertfordshire, UK: Garden City Press|isbn=978-0-584-10324-3}}</ref> Fully grown, the bright red [[pileus (mycology)|cap]] is usually around {{convert|8|–|20|cm|in|round=0.5|abbr=on}} in diameter, although larger specimens have been found. The red colour may fade after rain and in older mushrooms.
The free [[lamella (mycology)|gills]] are white, as is the [[spore print]]. The oval spores measure 9–13 by 6.5–9 [[micrometre|μm]]; they do not turn blue with the application of [[Melzer's reagent|iodine]].<ref name="arora86"/> The [[stipe (mycology)|stipe]] is white, {{convert|5|–|20|cm|in|abbr=on}} high by {{convert|1|–|2|cm|in|round=0.5|abbr=on}} wide, and has the slightly brittle, fibrous texture typical of many large mushrooms. At the base is a [[Volva (mycology)|bulb]] that bears universal veil remnants in the form of two to four distinct rings or ruffs. Between the basal universal veil remnants and gills are remnants of the [[partial veil]] (which covers the gills during development) in the form of a white [[annulus (mycology)|ring]]. It can be quite wide and flaccid with age. There is generally no associated smell other than a mild earthiness.<ref name = "Ultimatemush">{{cite book| author = Jordan P|author2=Wheeler S.| year = 2001 | title = The ultimate mushroom book | publisher = Hermes House | isbn = 978-0-8317-3080-2}}</ref><ref name=Phillips06>{{cite book | author= Phillips R.| year = 2006 | title = Mushrooms | publisher = Pan MacMillan | isbn = 978-0-330-44237-4|page=140}}</ref>
Although very distinctive in appearance, the fly agaric has been mistaken for other yellow to red mushroom species in the Americas, such as ''[[Armillaria]]'' cf. ''mellea'' and the edible ''Amanita basii''—a Mexican species similar to ''[[Amanita caesarea|A. caesarea]]'' of Europe.

Fly agarics are known for the unpredictability of their effects.

In cases of serious poisoning the mushroom causes [[delirium]], somewhat similar in effect to [[anticholinergic]] poisoning (such as that caused by ''[[Datura stramonium]]''), characterised by bouts of marked [[Psychomotor agitation|agitation]] with confusion, hallucinations, and irritability followed by periods of [[central nervous system]] depression.

There is no antidote, and supportive care is the mainstay of further treatment for intoxication.

===Psychoactive use===
[[File:Mushroom in the Hills of Adelaide.jpg|alt=Amanita muscaria in Mount Lofty, South Australia|thumb|Photographed in Mount Lofty Botanic Gardens, Adelaide Hills, South Australia]]
The wide range of [[Psychoactive drug|psychoactive]] effects have been variously described as [[depressant]], [[sedative]]-[[hypnotic]], [[Psychedelic drug|psychedelic]], [[dissociative]], or [[deliriant]]; [[Paradoxical reaction|paradoxical effect]]s such as [[Stimulant|stimulation]] may occur however. Perceptual phenomena such as [[synesthesia]], [[macropsia]], and [[micropsia]] may occur; the latter two effects may occur either simultaneously or alternatingly, as part of [[Alice in Wonderland syndrome]], collectively known as dysmetropsia, along with related distortions [[pelopsia]] and [[teleopsia]]. Some users report [[lucid dream]]ing under the influence of its hypnotic effects. Unlike ''[[Psilocybe cubensis]]'', ''A. muscaria'' cannot be commercially [[Fungiculture|cultivated]], due to its [[mycorrhiza]]l relationship with the roots of [[pine]] trees. However, following the outlawing of [[psilocybin mushroom]]s in the United Kingdom in 2006, the sale of the still legal ''A. muscaria'' began increasing.<ref name=EMC2006>{{cite book|title=Hallucinogenic mushrooms an emerging trend case study.|date=2006|publisher=European Monitoring Centre for Drugs and Drug Addiction|location=Lisbon|isbn=978-92-9168-249-2|url=http://www.emcdda.europa.eu/attachements.cfm/att_31215_EN_TP_Hallucinogenic_mushrooms.pdf}}</ref>{{rp|17}}
Professor [[Marija Gimbutienė]], a renowned Lithuanian historian, reported to [[R. Gordon Wasson]] on the use of this mushroom in Lithuania. In remote areas of [[Lithuania]], ''Amanita muscaria'' has been consumed at [[wedding feast]]s, in which mushrooms were mixed with [[vodka]]. The professor also reported that the Lithuanians used to export ''A. muscaria'' to the [[Sami people|Sami]] in the Far North for use in [[shamanic]] rituals.

===Siberia===
[[File:Amanita muscaria. Eastern Siberia.jpg|thumb|upright|''Amanita muscaria'', Eastern Siberia]]
''Amanita muscaria'' was widely used as an [[entheogen]] by many of the [[indigenous peoples of Siberia]]. Its use was known among almost all of the [[Uralic languages|Uralic]]-speaking peoples of western Siberia and the [[Paleosiberian]]-speaking peoples of the [[Russian Far East]]. There are only isolated reports of ''A. muscaria'' use among the [[Tungusic peoples|Tungusic]] and [[Turkic peoples]] of central Siberia and it is believed that on the whole entheogenic use of ''A. muscaria'' was not practised by these peoples.<ref name="nyberg1">{{cite journal|author=Nyberg, H.|year=1992|title=Religious use of hallucinogenic fungi: A comparison between Siberian and Mesoamerican Cultures|journal=Karstenia|volume=32|issue=71–80|pages=71–80|url=http://www.funga.fi/Karstenia/Karstenia%2032-2%201992-4.pdf|doi=10.29203/ka.1992.294|access-date=2018-05-15|archive-url=https://web.archive.org/web/20180515183752/http://www.funga.fi/Karstenia/Karstenia%2032-2%201992-4.pdf|archive-date=2018-05-15|url-status=dead}}</ref> In western Siberia, the use of ''A. muscaria'' was restricted to shamans, who used it as an alternative method of achieving a [[trance]] state. (Normally, Siberian shamans achieve trance by prolonged drumming and dancing.) In eastern Siberia, ''A. muscaria'' was used by both shamans and laypeople alike, and was used recreationally as well as religiously.<ref name="nyberg1" /> In eastern Siberia, the [[shamanism|shaman]] would take the mushrooms, and others would drink his urine.<ref name=Wasson1968/>{{rp|161}} This urine, still containing psychoactive elements, may be more potent than the ''A. muscaria'' mushrooms with fewer negative effects such as sweating and twitching, suggesting that the initial user may act as a screening filter for other components in the mushroom.<ref name="Diaz">{{cite book|author=Diaz, J.|title=How Drugs Influence Behavior: A Neurobehavioral Approach|publisher=Prentice Hall|location=Upper Saddle River, N.J.|year=1996|isbn=978-0-02-328764-0 }}</ref>
The [[Koryaks|Koryak]] of eastern Siberia have a story about the fly agaric (''wapaq'') which enabled Big Raven to carry a whale to its home. In the story, the deity ''Vahiyinin'' ("Existence") spat onto earth, and his [[spittle]] became the ''wapaq'', and his saliva becomes the warts. After experiencing the power of the ''wapaq'', Raven was so exhilarated that he told it to grow forever on earth so his children, the people, could learn from it.<ref name = "Ramsbottom45">Ramsbottom, p 45.</ref> Among the [[Koryaks]], one report said that the poor would consume the urine of the wealthy, who could afford to buy the mushrooms.<ref name=Wasson1968/>{{rp|234–35}}

===Vikings===
The notion that [[Viking]]s used ''A. muscaria'' to produce their [[berserker]] rages was first suggested by the Swedish professor [[Samuel Ödmann]] in 1784.<ref>{{in lang|sv}} Ödmann S.

The notion has become widespread since the 19th century, but no contemporary sources mention this use or anything similar in their description of berserkers.

==Fly trap==
''Amanita muscaria'' is traditionally used for catching flies possibly due to its content of [[ibotenic acid]] and [[muscimol]].
Recently, an analysis of nine different methods for preparing ''A. muscaria'' for catching flies in [[Slovenia]] have shown that the release of ibotenic acid and muscimol did not depend on the solvent (milk or water) and that thermal and mechanical processing led to faster extraction of ibotenic acid and muscimol.<ref>{{cite journal | author = Lumpert | year = 2016 | title = Catching flies with Amanita muscaria: traditional recipes from Slovenia and their efficacy in the extraction of ibotenic acid | doi = 10.1016/j.jep.2016.04.009 | journal = Journal of Ethnopharmacology | volume = 187 | pages = 1–8 | pmid=27063872}}</ref>

===Soma===
{{See also|Botanical identity of Soma-Haoma}}
In 1968, [[R. Gordon Wasson]] proposed that ''A. muscaria'' was the ''[[Soma (drink)|soma]]'' talked about in the [[Rigveda]] of India,<ref name=Wasson1968/>{{rp|10}} a claim which received widespread publicity and popular support at the time.<ref name=Letcher145>Letcher, p 145.</ref> He noted that descriptions of ''Soma'' omitted any description of roots, stems or seeds, which suggested a mushroom,<ref name=Wasson1968/>{{rp|18}} and used the adjective ''hári'' "dazzling" or "flaming" which the author interprets as meaning red.<ref name=Wasson1968/>{{rp|36–37}} 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 the mushroom having been brought in with the Aryan invaders from the north.<ref name=Wasson1968/>{{rp|22–24}} Indian scholars Santosh Kumar Dash and Sachinanda Padhy pointed out that both eating of mushrooms and drinking of urine were proscribed, using as a source the ''[[Manusmṛti]]''.<ref name=Letcher146>Letcher, p 146.</ref>
In 1971, Vedic scholar John Brough from Cambridge University rejected Wasson's theory and noted that the language was too vague to determine a description of Soma.<ref>{{cite journal|doi=10.1017/S0041977X0012957X|author=Brough, J.|title=Soma and ''Amanita muscaria''|journal=Bulletin of the School of Oriental and African Studies|volume=34|issue=2|year=1971|pages=331–62}}</ref> In his 1976 survey, ''Hallucinogens and Culture'', anthropologist Peter T.

Philologist, archeologist, and [[Dead Sea Scrolls]] scholar [[John Marco Allegro]] postulated that early Christian [[theology]] was derived from a fertility cult revolving around the [[entheogen]]ic consumption of ''A. muscaria'' in his 1970 book ''[[The Sacred Mushroom and the Cross]]'',<ref>

The book was roundly criticized by academics and theologians, including [[Godfrey Rolles Driver|Sir Godfrey Driver]], Emeritus Professor of Semitic Philology at [[Oxford University]], and [[Henry Chadwick (theologian)|Henry Chadwick]], the Dean of [[Christ Church, Oxford]].<ref name="Letcher, p 160">Letcher, p 160.</ref> Christian author John C. King wrote a detailed rebuttal of Allegro's theory in the 1970 book ''A Christian View of the Mushroom Myth''; he notes that neither fly agarics nor their host trees are found in the [[Middle East]], even though cedars and pines are found there, and highlights the tenuous nature of the links between biblical and Sumerian names coined by Allegro. He concludes that if the theory were true, the use of the mushroom must have been "the best kept secret in the world" as it was so well concealed for two thousand years.<ref>{{cite book|author=King, J.

[http://bayareamushrooms.org/education/further_reflections_amanita_muscaria.html "Further Reflections on Amanita muscaria as an Edible Species"]</ref> the consumption of detoxified ''A. muscaria'' has been practiced in some parts of 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 populariser and advocate of ''A. muscaria'' consumption, comparing it to [[manioc]], an important food source in tropical South America that must be detoxified before consumption.<ref name="RubArora"/>
Use of this mushroom as a food source also seems to have existed in North America. A classic description of this use of ''A. muscaria'' by an [[African-American]] mushroom seller in Washington, D.C., in the late 19th century is described by American botanist [[Frederick Vernon Coville]]. In this case, the mushroom, after parboiling, and soaking in vinegar, is made into a mushroom sauce for steak.<ref>Coville, F. V. 1898. ''Observations on Recent Cases of Mushroom Poisoning in the District of Columbia''. United States Department of Agriculture, Division of Botany. U.S. Government Printing office, Washington, D.C.</ref> It is also consumed as a food in parts of Japan. The most well-known current use as an edible mushroom is in [[Nagano Prefecture]], Japan.

A 2008 paper by food historian William Rubel and mycologist David Arora gives a history of consumption of ''A. muscaria'' as a food and describes detoxification methods. They advocate that ''Amanita muscaria'' be described in field guides as an edible mushroom, though accompanied by a description on how to detoxify it. The authors state that the widespread descriptions in field guides of this mushroom as poisonous is a reflection of [[cultural bias]], as several other popular edible species, notably [[morels]], are toxic unless properly cooked.<ref name="RubArora"/>

[[William Jackson Hooker|Hook]]. The 1987 edition of the [[International Code of Botanical Nomenclature]] changed the rules on the starting date and primary work for names of fungi, and names can now be considered valid as far back as May 1, 1753, the date of publication of Linnaeus's work.<ref>{{cite book | author = Esser K|author2=Lemke PA | title = The Mycota: a comprehensive treatise on fungi as experimental systems for basic and applied research | publisher = Springer | year= 1994| page = 181| isbn = 978-3-540-66493-2}}</ref> Hence, Linnaeus and Lamarck are now taken as the namers of ''Amanita muscaria'' (L.)

''Amanita muscaria'' is the [[type species]] of the genus. By extension, it is also the type species of ''Amanita'' [[subgenus]] ''Amanita'', as well as section ''Amanita'' within this subgenus. ''Amanita'' subgenus ''Amanita'' includes all ''Amanita'' with [[inamyloid]] spores. ''Amanita'' [[Section (botany)|section]] ''Amanita'' includes the species with patchy [[universal veil]] remnants, including a [[Volva (mycology)|volva]] that is reduced to a series of concentric rings, and the veil remnants on the [[pileus (mycology)|cap]] to a series of patches or warts.

====Controversy====
[[File:Amanita muscaria var. formosa sensu Thiers.jpg|thumb|right|upright|''Amanita muscaria'' var. ''formosa'' is now a synonym for ''Amanita muscaria'' var. ''guessowii''.<ref name=tulloss2 /><!-- defined by Template:Amanita variety -->]]
''Amanita muscaria'' varies considerably in its morphology, and many authorities recognize several subspecies or varieties within the species. In ''The Agaricales in Modern Taxonomy'', German mycologist [[Rolf Singer]] listed three subspecies, though without description: ''A. muscaria'' ssp. ''muscaria'', ''A. muscaria'' ssp. ''americana'', and ''A. muscaria'' ssp. ''flavivolvata''.<ref name=singer/>
However, a 2006 molecular phylogenetic study of different regional populations of ''A. muscaria'' by mycologist József Geml and colleagues found three distinct [[clade]]s within this species representing, roughly, Eurasian, Eurasian "subalpine", and North American populations. Specimens belonging to all three clades have been found in Alaska; this has led to the hypothesis that this was the centre of diversification for this species. The study also looked at four named varieties of the 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 [[Polymorphism (biology)|polymorphisms]] rather than distinct subspecies or varieties.<ref name="Geml06">{{cite journal|author=Geml J |author2=Laursen GA |author3=O'Neill K |author4=Nusbaum HC |author5=Taylor DL |title=Beringian origins and cryptic speciation events in the fly agaric (''Amanita muscaria'') |journal=Molecular Ecology |volume=15 |issue=1 |pages=225–39 |date=January 2006 |pmid=16367842 |doi=10.1111/j.1365-294X.2005.02799.x |url=http://www.lter.uaf.edu/pdf/1190_Geml_Laursen_2006.pdf |url-status=dead |archive-url=https://web.archive.org/web/20110716142858/http://www.lter.uaf.edu/pdf/1190_Geml_Laursen_2006.pdf |archive-date=2011-07-16 |citeseerx=10.1.1.420.2327 |s2cid=10246338 }}</ref> Further molecular study by Geml and colleagues published in 2008 show that these three genetic groups, plus a fourth associated with oak–hickory–pine forest in the southeastern United States and two more on [[Santa Cruz Island]] in California, are delineated from each other enough genetically to be considered separate species.
