Clitocybe
Scientific classification
Kingdom:	Fungi

Order:	Agaricales
Family:	Tricholomataceae
Genus:	Clitocybe (Fr.) Staude[1]
Type species
Clitocybe nebularis (Batsch) P. Kumm.

Hundreds of species of mushrooms compose the fungus genus Clitocybe. They are characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter.

Clitocybe means sloping head.

A few members of the genus are considered edible; many others are poisonous, containing the toxin muscarine among others. Distinguishing individual species of Clitocybe is generally prohibitively difficult to non-experts, requiring the analysis of microscopic characters. Therefore, with the exception of a few charismatic and readily identified members, Clitocybe mushrooms are rarely collected for consumption.

Recent molecular work has shown the genus to be polyphyletic, with many members seemingly distantly related and other fungi, such as the field blewit and wood blewit, now known as Clitocybe saeva and C. nuda respectively, are more closely related. As C. nebularis is the type species^[2], those most distantly related to it would be likely to be reclassified in the future.

[edit] Toxicity

The consumption of two species, Clitocybe acromelalga from Japan,^[3] and Clitocybe amoenolens from France,^[4] has led to several cases of mushroom-induced erythromelalgia which lasted from 8 days to 5 months.^[5]

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 rivolusa, contain muscarine in deadly amounts, and deaths have been recorded for eating those two Clitocybe species.
