Identification

Hairy Oyster Mushroom is a widely distributed and not uncommon gilled polypore. It occurs in Eastern Europe, North and South America, and Japan. It is found from May through November, alone, in groups, or in overlapping clusters or rosettes, on recently dead hardwood logs and stumps. Sometimes it appears to be growing on the ground but is actually attached to burried wood. It is saprobic, obtaining its nutrients from decaying wood.

When it first appears the cap is convex and the margin is tightly rolled under. When mature, the cap is ¾ to 3 wide, to thick, and usually depressed above the point where the stem is attached. It may be fan-shaped on the side of a log or stump, vase-like, or round or irregular in outline and forming rosettes on the ground or a horizontal surface. It is flushed with purple at first but fades in the sun, often on the first day. to reddish-, pinkish-, or orangish-brown or tan. The upper surface is dry and is densely covered with 1 32 to 1 16 (1 to 2 mm) long hairs.

The stalk, when present, is to ¾ long, up to wide, and usually off-center or at one side. It is tough, densely hairy, and colored like the cap.

The gills are close together, narrow, and run down the stalk (decurrent). They are purple at first, soon turning white, and eventually fading to tan. The spore print is white.

Hairy Oyster Mushroom is edible but the flesh is tough, thin, hairy, and sometimes bitter.

What’s in a Name?
Hairy Oyster Mushroom looks similar to to a small Oyster Mushroom, only hairy. However, recent research shows them to not evenly closely related. This is an example of convergent evolution, where similar features, in this case gills, evolved independently.

Taxonomy
This fungus was named Lentinus lecomtei when it was first described in 1751. In 1981 it was moved to the genus Panus and in 1983 the name was changed to Panus strigosus. However, that name had been previously used and discarded. In 2012, to remove confusion with the other species, the name was changed to Panus neostrigosus. Other names used for this species, and still in use today by some authors and fungaria, are Lentinus strigosus, Panus lecomtei, and Panus rudis.
