Clitocybe acromelalga

Clitocybe acromelalga is a basidiomycete fungus of the large genus Clitocybe found in Japan. It was discovered to be poisonous in 1918, when symptoms of mushroom poisoning occurred within three days of consumption. It had been mistaken for the edible Tawny Funnel Cap Paralepista flaccida (formerly Lepista inversa). Consumption of a related species, C. amoenolens from France has resulted in the same condition.
