Leptonia rosea

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)

Spores pink or reddish

Terrestrial (occasionally on rotting wood on the ground)
Gills attached (notched, adnate, or subdecurrent), sometimes almost free in small mushrooms

Cap up to 2" across; broadly convex; usually slightly scaly, but not silky; either
black or very dark blue or purple and slightly iridescent, or
(very rarely) brightly colored, or
(equally rarely) a little of each
Sometimes smelling awful or like bubble gum, but not like bleach
Stalk fragile, fibrous

Either an interesting color (yellowish green and pink come to mind) or with an interesting (usually in the negative sense) smell
Rare
