Amanita ibotengutake is a species of agaric fungus in the family Amanitaceae native to Japan. It was first described in 2002 as distinct on a genetic level from A. pantherina, and earlier has been classified under that name.
The scientific name derives from Japanese name of A. strobiliformis, ibotengutake (ç£天çÂÂè¸, lit. "wart tengu mushroom"), which inspired the name of ibotenic acid. A. ibotengutake contains ibotenic acid and muscimol, rendering it toxic and psychoactive.
