visited the same trunk, but found they had begun to decay. It
is sometimes called Poria obliqua.

_Polyporus graveolens. Fr._

[Illustration: Figure 334.--Polyporus graveolens.]

Graveolens means strong scented. Corky or woody and extremely hard, very
closely imbricated and connate, forming a subglobose polycephalous mass,
Figure 334. Pileoli innumerable, inflexed and appressed, plicate, brown.

Pores concealed, very minute, round, pale-brown, the dissepiments thick
and obtuse. _Morgan._

This is a very interesting plant because of its peculiar mode of growth.
It is found in woods or clearings on dead logs or on standing dead
trees. In some parts of the state it is quite common. From the
illustration, Figure 334, it will be seen that the plant consists of an
innumerable number of pileoli forming a subglobose or elongated mass.
They are frequently three to six inches in diameter and several inches
long. I have seen them very much elongated on standing trees. When it is
young and growing it is shiny in appearance and has a reddish and
sometimes a purplish tint. The inner substance is ferruginous but
covered with a hard brown crust. The pores are brown, and when examined
with the glass are seen to be lined with a very fine pubescence. The
imbricated form of the pileoli show very plainly in the illustration.

_Polyporus brumalis. Fr._

THE WINTER POLYPORUS.

[Illustration: Figure 335.--Polyporus brumalis.]

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, 5-6x2u.

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.

_Polyporus rufescens. Fr._

THE RUFESCENT POLYPORUS.

Rufescens, becoming red. The pileus is flesh-colored, spongy, soft,
unequal, hairy or woolly.

The pores are large, sinuose and torn, white or flesh-colored.

The stem is short, irregular, tuberous at the base. Spores ell
