Crepidotus mollis

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 less than an inch across; hygrophanous; usually darker shade(s) of brown: more or less caramel-colored
Sometimes lacking a stem

Growing shelf-like from dead hardwoods
Cap often an inch or less across; always less than 3"
Stem absent or very stubby. Usually just attached to the substrate by a point on the cap from which the gills diverge
