Amanita phalloides

Amanita phalloides (NL: Groene knolamaniet / EN: Death cap / DE: Grüne Knollenblätterpilz, Grüne Gift-Wulstling / FR: Amanite phalloïde , Oronge verte, Calice de la mort) is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Widely distributed across Europe, A. phalloides forms ectomycorrhizas with various broadleaved trees. Coincidentally, 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 is estimated that 30 grams, or half a cap, of this mushroom is enough to kill a human. It has been involved in the majority of human deaths from mushroom poisoning, possibly including the deaths of 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.

Interesting information. It could make one very leery of eating wild mushrooms.

@Julie L. Brown: It can be very dangerous indeed ...
Hope you have a great 2012, Julie !
