Genus (Fungi): Amanita

The genus Amanita contains about 600 species of agarics, including some of the most toxic known mushrooms found worldwide, as well as some well-regarded edible species. This genus is responsible for approximately 95% of the fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is α-amanitin.

The genus also contains many edible mushrooms, but mycologists discourage mushroom hunters, other than knowledgeable experts, from selecting any of these for human consumption. Nonetheless, in some cultures, the larger local edible species of Amanita are mainstays of the markets in the local growing season. Samples of this are Amanita zambiana and other fleshy species in central Africa, A. basii and similar species in Mexico, A. caesarea and the "Blusher" Amanita rubescens in Europe, and A. chepangiana in South-East Asia. Other species are used for coloring sauces, such as the red A. jacksonii, with a range from eastern Canada to eastern Mexico.

Many species are of unknown edibility, especially in countries such as Australia, where many fungi are little-known.
