Identification

This is a widespread and fairly common bracket fungus. It is found in dense, overlapping rows or fused clusters on dead hardwoods. It is rarely found on conifers. It usually takes the form of bracket on the side of a tree or log but occasionally appears as a crust on the underside of a dead branch.

The fruiting body is a medium-sized, unstalked bracket. The bracket is elongated or fan-shaped, flat or wavy, up to 4 wide, and up to 2 deep. It is leathery and flexible or corky when fresh, becoming rigid and inflexible when dry. The upper surface is dry and white to tan, smoky gray, or grayish-brown. It is usually weakly concentrically zoned in shades of brown and gray, sometimes unzoned. When young, it is velvety-hairy or finely hairy and the margins are whitish. When mature, it is nearly hairless and the margins turn brown to black, giving a scorched appearance.

There is no stem.

The underside is densely covered with spore-bearing pores. It is whitish when young, bruising gray, and turning smoky gray to blackish at maturity. The pores are very minute and barely visible without a hand lens. There are 5 to 7 pores per millimeter. The spore tubes are no more than 1 16 deep.

The flesh is white, tough, and corky or leathery. It is not poisonous but is inedible due to a tough texture and a sour taste.

The spore print is white.
