_Polyporus cuticularis. Fr._

Pileus is quite thin, spongy, fleshy, then dry; plane, hairy-tomentose,
ferruginous, then blackish-brown; margin fibrous, fimbriate, internally
loose and parallel, fibrous.

The pores are long, quite small, pale, then ochraceous; pores longer
than the thickness of the flesh. The spores are yellow or ochraceous,
very abundant, 7x4-5u. The hairs on the pileus are three-cleft.

This is very frequent in beech woods about Chillicothe. Found in
September and October.

_Polyporus circinatus. Fr._

THE ROUND POLYPORUS. EDIBLE.

Circinatus is from _circinus_, a pair of compasses, hence means rounded
like a circle.

The pileus is three to four inches across, with a double cap, one cap
within another, both being compact, thick, round, plane, zoneless,
velvety, rusty-yellow to reddish-brown, the flesh being of the same
color. The upper cap is pliable, compact, soft, and covered with a soft
tomentum, the lower cap, contiguous with the stem, is woody and corky.

The pores are decurrent, extending down the stem, entire, rather small,
dusky-gray.

The stem is short and rather thick, often swollen, covered with a
reddish-brown tomentum.

This is an odd but handsome species and easily determined because of its
double cap. It is said to prefer fir woods, but I have frequently found
it in oak woods. It grows on the ground, and when young and fresh the
pilei are said to be good. I have never found more than one specimen at
a time and never in a condition to eat, though good authorities say it
is edible when young and tender. Found in September and October.

_Polyporus adustus. Fr._

Adustus means scorched, so called from the blackish color of margin.

The pileus is often imbricated; fleshy, tough, firm, thin, villous,
ash-color; margin straight, blackish.

The pores are minute, round, obtuse, whitish, soon ashy-brown.

It is abundant everywhere on fallen beech or on beech stumps. It is very
close to P. fumosus if it is not identical with it. It is found from
August to late fall.

_Polyporus resinosus._

[Illustration: Figure 331.--Polyporus resinosus. One-fourth natural
size.]

Pileus from three to six, and frequently eight, inches long; rich-brown,
varying from bright cinnamon to red, handsomely marked with delicate
pencilings radiating from the axis of growth; the color of the pileus
seems to form a binding about the edge of the light-gray pore surface,
which is closely punctur
