Paxillus atrotomentosus

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)

Gills not free
Spore print tan, orange, deep ochre, yellowish olive, olive brown, rusty or cinnamon brown or deep brown
Ring usually either absent or not membranous

Growing on wood

Cap usually more than 2" across, and sometimes up to 8; usually tan, yellow, or pumpkin-colored

Fruiting body tough
Gills often forking and cross-veined near the stalk; often easily separable from the cap
Cap usually 3-4" across; margin inrolled when young
Stalkless Brown, Olive, Orange or Tan Spored mushrooms go here if they are firm and substantial; small, flabby ones go in Crepidotus)

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

Diagnosis

• Cap up to 6" across; brown
  
• Stalk with a velvety coating of blackish-brown hairs

Microscropic Characters

• Spores 5-7 x 3-4.5 µm, many of them dextrinoid

Comments

The picture really should show it coming from wood
