Tricholomopsis rutilans

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.

Fruiting body containing fibers (usually in the stalk)

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

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

Growing on trees or dead wood, leaves, or sticks, or organic debris, often in moss

Shaped like a “normal mushroom”
Small and fragile to medium-sized, except for one large, grey-capped species

All or almost all of the fruiting body bright yellow to orange yellow
Often powdery, finely scaly, or furry
In one case, pictured here, just the gills are yellow

On dead coniferous wood
Cap not omphaloid, usually 2-4" across
No annulus
Usually, entire fruiting body yellow (sometimes buff), and the color is clearly yellow, as opposed to orange
Cap and stem may be covered with little pointy black, brown or reddish-brown tufts of fibrils, which hide most of the yellow surface

If there's just a few words or a microscopic feature here, a more thorough description can be found above.
