Leucopaxillus     Genus

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
