Tricholoma flavovirens

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 saponaceumTricholoma     Genus
All mushrooms with emarginate gills (as in picture) go here
Some yellowish coloration common, perhaps some colorful powder or scales on the cap and/or lower stem; sometimes with a partial veil and armilla (not an annulus).
If the mushroom has an ordinary annulus, you may have one of the Lepiotaceae

Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page.
If there's just a few words or a microscopic feature here, a more thorough description can be found above.

Just the ones in the foreground. The brown things in back are something else
There are many yellow-capped Tricholomas; if we start finding them around here, I will expand the key
