Discina perlata, commonly known as "Pig's Ears" is a brown to tannish, wrinkled, cup- or ear-shaped fungus, sometimes with short, stout stalk. The spores of D. perlata are quite similar to those of mushrooms in the genus Gyromitra, so that some mycologists place it there. It is considered an edible however like with all mushrooms which are wild crafted must be not only properly identified, but also caution should be taken against possible accidental poisoning or allergic reactions.

Description
Discina perlata is a brown to tan-brown mushroom, with a wrinkled, cup- or ear- shaped cap. It sometimes has a short, stout stipe. The Cup measures 1⅝ - 4 in. (4 - 10 cm) wide; with a disc-like, whitish exterior, and a dark brown to tan interior. The cup is often wrinkled to convoluted, with the edges turned downward. The flesh is brittle. The stipe (when present) is ¼ - ⅜ in. (0.5 - 1 cm.) long and thick; it is brownish-tan in color.
Microscopic characteristics
The spores are 30 - 35 x 12 - 14 ɥm; Spindle shaped, minutely warted, with 3 oil drops and knobs at each end, located in the cup.
Edibility
It is edible however with caution.
Similar species
Disciotis venosa is more deeply veined, and has smooth spores; it is typically found in deciduous woods. Other similar species of Discina must be differentiated microscopically.
Habitat and distribution
It is found singularly or in groups, on humus or rotten wood in coniferous areas; near melting snowbanks in western mountains. Its range is from Northeastern United States, Northwestern United States, and California. It comes into fruiting from May-July.
