Amanita phalloides is a poisonous basidiomycete fungus, one of many in
the genus Amanita. Widely distributed across Europe, A. phalloides
associates with various deciduous and coniferous trees. Adaptations
have expanded its range outside of Europe after it was accidentally
introduced alongside oak, chestnut, and pine. The large fruiting
bodies (i.e. the mushrooms) appear in summer and autumn; the caps are
generally greenish in colour, with a white stipe and gills.
Unfortunately, these toxic mushrooms resemble several edible species
commonly consumed by humans, increasing the risk of accidental
poisoning. A. phalloides is one of the most poisonous of all known
toadstools. It has been involved in the majority of human deaths from
mushroom poisoning, including the Roman Emperor Claudius and Holy
Roman Emperor Charles VI. It has been the subject of much research and
many of its biologically active agents have been isolated. The
principal toxic constituent is α-amanitin, which damages the liver and
kidneys, often fatally. No antidote is known.
