Stereum purpureum. Pers.
Purpureum means purple, from the color of the plant.
Coriaceous but pliant, effuso-reflexed, more or less imbricated, tomentose, zoned, whitish or pallid.
The hymenium is naked, smooth, even; in color a pale clear purple, becoming dingy ochraceous, with only a tinge of purple, when dry. The spores are elliptical, 7–8×4µ.
I found the plant to be very abundant in December and January, in 1906–7, on soft wood corded up at the paper mill in Chillicothe, the weather being mild and damp.
Stereum compactum.
Broadly effused, coriaceous, often imbricated and often laterally joined, pileus thin, zoned, finely strigose, the zones grayish-white and cinnamon-brown.
The hymenium is smooth, cream-white.
This species is found on decayed limbs and trunks of trees.
