Key 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.
Fruiting body containing fibers (usually in the stalk)
White 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
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
Terrestrial Trich Subfamily
Growing on the ground
Woodland Normal Trich Tribe
Found in woods
Tricholoma-like Fungi Subtribe
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
Tricholoma saponaceum (Fries) Kummer
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.
It's especially not fair to stick a single species here. If we find any, this will be turned into a section of about a dozen grey-capped Tricholomas
