Native throughout the temperate and boreal regions of the Northern Hemisphere, Amanita muscaria has been unintentionally introduced to many countries in the southern hemisphere, generally as a symbiont with pine plantations, and is now a true cosmopolitan species.
It associates 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.
