Bitter oyster

Description:

During the development of the fruit bodies, the mushrooms start out as tiny white knobs, which, over a period of one to three months, develop into fan- or kidney-shaped caps that measure up to 3 cm broad. The caps are orange-yellow to brownish, and attached to the decaying wood by short stubby stalks, up to about 1 x .5 cm, that are connected off-center or on the side of the caps. The stems are usually fuzzy-velvety with whitish, tan, or rusty brown fuzz. The gills are close, often forked with cross-veins and pale yellowish brown.

Habitat:

Habitat often in crowded tiers on dead branches or stumps, especially of oak.

Notes:
