Many mushroom species are poisonous to humans and cause a range of reactions including slight digestive problems, allergic reactions, hallucinations, severe organ failure, and death. Genera with mushrooms containing deadly toxins include "Conocybe", "Galerina", "Lepiota", and, the most infamous, "Amanita". The latter genus includes the destroying angel "(A.virosa)" and the death cap "(A.phalloides)", the most common cause of deadly mushroom poisoning. The false morel ("Gyromitra esculenta") is occasionally considered a delicacy when cooked, yet can be highly toxic when eaten raw. "Tricholoma equestre" was considered edible until it was implicated in serious poisonings causing rhabdomyolysis. Fly agaric mushrooms ("Amanita muscaria") also cause occasional non-fatal poisonings, mostly as a result of ingestion for its hallucinogenic properties.
