Not Blackfoot     Section

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.

Fertile surface usually a layer of vertical tubes, of which the mouths are visible as pores on the underside of the cap or shelf.
Fruiting bodies usually tougher or harder than the "normal" gilled mushrooms, being leathery, corky, or woody. But they can be quite tender while actively growing
Once grown, they do not decay easily, remaining on the substrate for months or years
They often grow on wood, although a few are terrestrial (even those are usually growing on buried wood)
Fruiting body is usually a flat shelf, or hoof-shaped, protruding directly from the substrate, although sometimes it may have a short stalk.
Some forms never grow away from the substrate at all, so that all that is visible of the fruiting body are the pores.
Sometimes the pores are so minute that the fertile surface seems solid, until you look closely

Growing on wood

Not fitting the other choices, fruiting body with well-developed stem

Cap lacking hard crusty upper surface or large, angular pores
Fruiting body flexible if it's not really thick

Diagnosis

• Stem not black anywhere

Narrow down your identification:

Thin-fleshed cap 3/8 - 3 1/4, golden-brown to dark brown, usually minutely scaly; margin fringed with delicate hairs

Thin-fleshed cap yellow brown to brown, velvety when young, with inrolled margin, 1/2 - 4" across
On dead hardwoods, especially birch
