Clitocybe

Clitocybe was originally proposed by Elias Fries in 1821 as a tribe in the genus Agaricus. Friedrich Staude elevated it to generic status in 1857. ==Toxicity==

The consumption of two species, Clitocybe acromelalga from Japan, and Clitocybe amoenolens from France, has led to several cases of mushroom-induced erythromelalgia which lasted from 8 days to 5 months. Many small Clitocybe species contain the toxin muscarine, which was originally found in small amounts in the famous fly agaric. However, the small white Clitocybe species contain muscarine in dangerous amounts, and two species in particular, the closely related Clitocybe dealbata and Clitocybe rivulosa, contain muscarine in such amounts that deaths have been recorded for eating those two Clitocybe species. ==Selected species==
