The consumption of two species, Clitocybe acromelalga from Japan,[7] and Clitocybe amoenolens from France,[8] has led to several cases of mushroom-induced erythromelalgia which lasted from 8 days to 5 months.[9]
Clitocybe odora
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.
