毒蠅傘
Amanita muscaria, commonly known as the fly agaric or fly amanita, is a basidiomycete of the genus "Amanita". It is also a muscimol mushroom. 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 and birch plantations, and is now a true cosmopolitan species. It associates with various deciduous and coniferous trees.
