Clitocybe amoenolens, commonly known as the poison dwarf bamboo mushroom, is a basidiomycete fungus of the large genus Clitocybe found in France. It was only recently described in 1975 by the French mycologist Malençon. It was discovered to be poisonous after several people had consumed specimens all found in the alpine Maurienne valley in the Savoie department over three years. They had mistaken it for the edible common funnel cap (C. gibba) or Blewit (Lepista inversa).[1]

A similar species from Japan, C. acromelalga had been discovered to be poisonous in 1918.[2]

The resulting syndrome of mushroom-induced erythromelalgia which lasted from 8 days to 5 months, although one person exhibited symptoms for three years.[3]
