Armillaria gallica

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

Fruiting body medium-sized to large
Cap grey to brown, sometimes with radiating with dark brown to black fibrils
All else white or concolorous with cap
Growing on wood or duff

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

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.

Diagnosis

• Usually growing on ground, not wood, in troops
  
• Annulus fibrillose, cottony
  
• Fruiting bodies only an inch or two across, often connected directly to rhizomorphs

• Cap with brown squamules, most thickly on the disk, but these wash away in the rain
