Brumalis is from bruma, which means winter; so called because it appears late, in cold weather. The specimens in Figure 335 were found in December.
The pileus is from one to three inches broad, nearly plane, slightly depressed in the center; somewhat fleshy and tough; dingy-brown, clothed with minute scales, becoming smooth, pallid.
The pores are oval, slightly angular, slender, acute, denticulate, white, 5–6×2µ.
The stem is short, thin, slightly bulbous at the base, hirsute or squamulose, pale, central.
It usually occurs singly but frequently you will find several in a group. Found on sticks and logs, they are quite hard to detach from their hosts. Too tough to eat. It equals Polyporus polyporus. (Retz) Merrill.
