Spongiosipes means a sponge-like foot. Pileus convex, soft,
spongy-tomentose, but tough in texture, rusty-brown, the lower stratum
firmer and more fibrous, but concolorous.

The spines are slender, one to two lines long, rusty-brown, becoming
darker with age.

The stem is hard and corky within, externally spongy-tomentose; colored
like the pileus, the central substance often transversely zoned,
especially near the top. Spores globose, nodulose, purplish-brown, 4-6
broad. Pileus one and a half to four inches broad. Stem one and a half
to three inches long, and four to eight lines thick. _Peck_, 50th Rep.

It is found in the woods, quite plentifully, about Chillicothe. I
referred it to H. ferrugineum for a long time, but not being satisfied,
sent some specimens to Dr. Peck, who classified it as H. spongiosipes.
It is edible but very tough. Found from July to October.

_Hydnum zonatum. Batsch._

THE ZONED HYDNUM.

[Illustration: Figure 370.--Hydnum zonatum.]

Zonatum, zoned. Ferruginous; pileus equally coriaceous, thin, expanded,
subinfundibuliform, zoned, becoming smooth; tough, almost leathery in
texture, having a surface of beautiful brown, silky lustre, and with
radiating striae; margin paler; sterile.

The stem is slender, nearly equal, floccose, bulbous at the base.

The spines are slender, pallid, then of the same color as the pileus,
equal. The spores are rough, globose, pale, 4u.

The spore-bearing spines are shown in the upper plants in Figure 370.
Two of them show coalesced caps, though the stems are separate. This is
the case with H. scrobiculatum and H. spongiosipes. The plants in Figure
370 were collected by the roadside in woods on the State Farm, near
Lancaster, and photographed by Dr. Kellerman.

_Hydnum scrobiculatum. Fr._

[Illustration: Figure 371.--Hydnum scrobiculatum. Two-thirds
natural-size.]

Scrobiculatum means marked with a ditch or trench; so called from the
rough condition of the cap. The pileus is from one to three inches
broad, corky, convex, then plane, sometimes slightly depressed; tough in
texture, rusty-brown; the surface of the cap usually quite rough, marked
with ridges or trenches, flesh ferruginous.

The spines are short, rusty-brown, becoming dark with age.

The stem is firm, one to two inches long, unequal, rusty-brown, often
covered with a dense tomentum.

This species is very plentiful in our woods, among the leaves under
beech trees.
