Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)

Amanita onustaWhite Spored     Suborder
Spore print "light-colored": white or buff, sometimes tinged with pink or tan. Greenish and (except for the Russulales) yellow spore prints also go here
Stalk fibrous, not fracturing like a piece of chalk

TricholomataceaeTricholomataceae     Family
None of the special features distinguishing the other white-spored genera:
Gills not free, as in the Lepiotas and Amanitas
Basidia not extra-long, as in the Hygrophoraceae
Spores smooth, except for Lentinellus

TricholomaTerrestrial Trich     Subfamily
Growing on the ground

Clitocybe nebularisWoodland Normal Trich     Tribe
Found in woods
Not rooting

Clitocybe nebularisClitocybe-like Fungi     Subtribe
Gills attached to decurrent
Coloration usually white to greyish brown, sometimes purple or with purple tones
Never with a ring of any kind

Clitocybe squamulosaClitocybe     Genus
Gills attached to decurrent, crowded
Cap glabrous, small to very large; often aging into a funnel shape
Spore print often tinged with pink or buff
Look for things here if they have non-free gills and don't fit the other taxa

Clitocybe nuda



This is the section most people are interested in, so I've tried to provide a strong selection of species, to try and keep folks from poisoning themselves. Be sure to check that what you have isn't one of those pretty purple cortinarii (see Sericeocybe and Phlegmacium)
I am not totally convinced convinced that these are really separate species: after all, we know that blewits tend to get less purple the longer they grow, and that's the pattern of this taxon: the larger they are, the less purple
This is not Singer's genus Lepista. Singer bases his taxon on spore morphology and color; mine is an artificial one (though perhaps not more so), designed solely to help prevent people from poisoning themselves

Narrow down your identification:

Clitocybe irina
Entire fruiting body white at first, becoming pale pinkish buff, except for:
Stalk aging or bruising brown; sometimes swollen at base
In woods, especially under spruce

Clitocybe nudaClitocybe nuda
Entire fruiting body with some sort of purple tinge; even the mycelium that often binds the substrate around the base is often lilac

Clitocybe saevaClitocybe saeva
Purple only on the stalk

Clitocybe tarda
Like Clitocybe nuda, but slimmer, gracile; colors duller, learning more towards brownish and pinkish buff


Clitocybe robusta
