Common Names: Lilac oysterling
Its fruitbodies are characterized by a smooth, lilac- or tan-colored cap, and decurrent gills. The fungus is saprophytic and fruits on the decomposing wood of a wide variety of deciduous and coniferous trees. Despite being a gilled species, phylogenetic analysis has shown it is closely related to the pored species found in the family Polyporaceae.
The cap is 5 to 15 cm in diameter, and is initially convex, but later flattens or becomes centrally depressed in maturity. The cap is tan, lilac or reddish-brown, and smooth (glabrous); in age the surface may crack into small flattened scales. The cap margin is inrolled and often has a wavy or lobed outline. The flesh is tough and whitish. The gills are attached in a decurrently (running down the length of the stem), and are narrow and often forked. The gills initially have a violet tinge, but later become an or reddish-violet. The stem is 2 to 3 cm long and 1 to 3 cm thick, roughly the same color as the cap, but covered with violet hairs; it is attached to the cap laterally, or off-center. The spore print is white.
