Tricholoma     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

Tricholoma flavovirensTricholoma-like Fungi     Subtribe
Woodland habitat (mycorrhizal)
Stem fleshy, not rooting

Tricholoma     Genus     (Fries) Staude

Tricholoma saponaceum


Microscropic Characters


If the diagnosis seems vague to you, you are perceptive; this is a very variable group. Luckily, we don't have to stress about identifying them much in Illinois, as all Tricholomas are mycorrhizal forest creatures, rarely found here since our forests suck. On the theory that some of you may go to Wisconsin, Michigan, or some other place with good forests, I've provided three representative species, whch may end up getting expanded into three (artificial) sections of the genus

Narrow down your identification:

Tricholoma caligatumTricholoma caligatum
Cap with coarse scales and fibers
With an armilla; the part that sheathes the stem breaking up into patches as the stem grows

Tricholoma flavovirensTricholoma flavovirens
Cap yellow with darker center
Under pine
Often only partially emerging from the ground

Tricholoma saponaceumTricholoma saponaceum
Grey cap
