Poisonous species

Three of the most lethal mushrooms belong to the genus Amanita: the death cap (A. phalloides) and destroying angels (A. virosa, and A. verna); and two are from the genus Cortinarius: the deadly webcap (C. rubellus), and the fool's webcap (C. orellanus). These species cause the greatest number of fatalities. The principal toxins are alpha-amanitin in the genus Amanita and orellanine in the genus Cortinarius.

The following species may cause great discomfort, but are less often lethal.

* Amanita muscaria (fly agaric) poisonings rare, possibly because its unique and obvious appearance make it easily identifiable; however, its long history of use as an entheogen and new reports suggesting it is less toxic than once thought may suggest otherwise.
* Amanita pantherina (panther mushroom) Contains similar toxins as A. muscaria, but in higher quantities; first signs of distress occur after 8 to 12 hours; 8085% of victims survive.
* Amanita regalis symptoms generally mild
* Entoloma spp. highly poisonous, such as livid Entoloma (Entoloma sinuatum), Entoloma rhodopolium, and Entoloma nidorosum. First symptoms appear after 20 minutes to 4 hours.
* Galerina Some species contain alpha-amanitin (deadly poisonous)
* Many Inocybe spp. Inocybe fastigiata, Inocybe geophylla, and Inocybe patouillardii
* Some white Clitocybe First symptoms after 15 to 20 minutes
* Tiger Tricholoma no lasting effect after 2 to 6 hours of great pain.
* Sulfur tuft poisoning may be serious
* Omphalotus olearius mild
* False morel (Gyromitra esculenta) may not affect some people at all. Deadly poisonous when raw; harmless and delicious if correctly prepared.
* Brown roll-rim once thought edible, but now found to be destructive of red blood cells with regular or long-term consumption.
* Devil's Boletus (Boletus satanas)
* Purple Boletus (B. rhodoxanthus)
* Coprinus atramentarius
* Conocybe filaris contains amatoxins, sometimes thought to be a Psilocybe.
