Amanita amanita (scientific name: Amanita amanita), also known as Amanita amanita and Amanita toadstool, is a basidiomycete fungus with neurotoxic effect and is one of the Amanita genera. The fruiting body of fungi is relatively large. The width of the hat is 6-20 cm. The edge has obvious short edges, the surface is bright red or orange red, and there are white or yellowish granular scales. The folds are pure white, dense and free, with different lengths. Mushroom meat is white and red near the skin of the lid.
Poisonous fly umbrella is a global species, originally growing in pine trees and deciduous forests, spanning temperate and polar regions in the northern hemisphere, including temperate high-altitude areas, such as Hindu Kush, Mediterranean and Central America. A recent molecular biology research report pointed out that the ancestor group of the poisonous fly umbrella was in the Siberian-Bering land bridge area of the Tertiary, and extended to Asia, Europe and North America.
Although mushrooms usually grow in autumn, they are different according to different climates: in North America, the mushroom season is from summer to autumn, and on the Pacific coast, it is from autumn to early winter. Another kind of mushroom boletus reticulata is usually found in these similar places, and it often appears in the form of a fairy ring. Through the transportation of pine seedlings, toadstools fly widely to the southern hemisphere, including Australia, New Zealand, South Africa and South America.
