Tricholoma-like Fungi     Subtribe

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 the ground

Found in woods
Not rooting

Diagnosis

• Woodland habitat (mycorrhizal)
  
• Stem fleshy, not rooting

Narrow down your identification:

• 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

Lookalikes: Armillaria     Genus Cap brownish or yellowish, or a mixture of either of those two with grey Growth habit cestipose, sometimes in troops Fibrils often quite dense in center of cap, sparser towards the margin Annulus usually present Black rhizomorphs Agrocybe erebia Cap up to 2 1/4" across, with a low, broad umbo; dark brown or dark reddish brown; slimy or viscid when fresh; often drying in hygrophanous zones, with the disk and margin remaining darker than the tissue in between With a fragile but membranous partial veil forming a persistent annulus Gills often subdecurrent On the ground in cultivated areas and damp woods
