Overview

Amanita muscaria has many variations in regional subspecies which can be distinguished by their environment and physiology. [3]

Amanita muscaria subspecies

Image	Scientific name	Common name	Description
[3]	Amanita muscaria var. muscaria	Euro-Asian fly agaric	The muscaria variation has a bright red cap and originated from northern Europe and Asia. Cap may also be orange or yellow due to slow development of the purple pigment.
[4]	Amanita muscaria var. flavivolvata	American fly agaric	The flavivolvata variation is red with yellow to yellowish-white warts. It is found from southern Alaska down through Central America, all the way to Andean Colombia.
[5]	Amanita muscaria var. guessowii	American fly agaric (yellow variant)	The guessowii variation has a yellow to orange cap, with the center often having an orange or red gradient.
[6]	Amanita muscaria var. inzengae	Inzenga's fly agaric	The inzengae variation has a pale yellow to orange-yellow cap with yellowish warts and a tan stem.

Ecology

Fly agarlic has been used historically as a pesticide by combining the mushroom with milk and spraying on plants. The practice of using amanita muscaria for pest management in Germanic and Slavic speaking parts of Europe lead to the fungus claiming the common name "fly agarlic" for its ability to kill flies.[2]

Psychoactive and cultural uses

Amanita muscaria contains several active agents which can cause toxic and psychoactive reactions. Muscimol and ibotenic acid are two neurotoxins found in varying doses and ratios within the Amanita muscaria cap.[4][6] The hallucinogenic effects have been used in Asian and European shamanic rituals across many cultures and it's use in Sibera can be dated to over 16,000 years ago.[5]
