Hairy Curtain Crust is an extremely common, widely distributed, wood decaying, bracket fungi. It is saprobic, occurring on stumps, logs, and sticks of mostly hardwood trees, especially oak. It occasionally occurs on living trees and conifers. It is highly variable in form and color, making positive identification difficult. It may be found in groups, rows, shelves, or dense overlapping clusters.

There is no stalk.

The fruiting body is often a thin, semicircular or fan-shaped, 3 ⁄16″ to 1½″ wide or slightly wider bracket (cap). It is leathery and pliant when moist, rigid when dry. It may be flat, wavy, or curved up at the sides in the shape of a sliced funnel. Sometimes adjacent brackets fuse together forming a lobed shelf up to 4″ long or longer. The upper surface is dry and concentrically zoned with different colors and textures. When young and moist it is shades orangish-brown, reddish-brown, tawny, or cinnamon. When dry it is buff to gray. Older specimens may develop greenish shades due to a covering of algae. It is densely covered with velvety or appressed hairs but often hairless or nearly hairless near the margins. As it ages the hairs wear away.

The under surface is smooth or slightly bumpy, with no layer of pores or tubes. It is orange, orangish-buff or tawny to yellow or yellowish-orange with a brownish tinge. It often becomes dark brown to chestnut brown with age.

The flesh is thin, tough, and inedible. When cut, young caps do not bleed a red liquid.

The spore print is white but difficult to obtain.

In groups, rows, or dense overlapping clusters on stumps, logs, and sticks of mostly hardwood trees, especially oak. Occasionally on living trees and conifers.
