in the woods on trunks and sticks after a
rain in July, August, and September. It is not as plentiful as Hydnum
spongiosipes and H. scrobiculatum. It is an attractive plant when seen
in the woods.

_Hydnum ochraceum. P._

OCHREY HYDNUM.

Small, at first entirely resupinate, gradually reflexed, and somewhat
repand, at first sparingly clothed with dirty-white down, at length
rugose; one to three inches broad. The spines are short, entire,
becoming pale. _Fries._

It is occasionally found on decayed sticks in the woods.

_Hydnum pulcherrimum. B. & C._

MOST BEAUTIFUL HYDNUM.

[Illustration: Figure 375.--Hydnum pulcherrimum. Showing the under side
of one of the pileoli.]

Pulcherrimum is the superlative of _pulcher_, beautiful.

The pileus is fleshy, somewhat fibrous, alutaceus, hirsute; the margin
thin, entire, incurved.

The aculei short, crowded, equal.

It is found on beech wood, frequently imbricated and laterally
confluent; a single pileus two to five inches in breadth and projecting
two to four inches. The spines are rather short, not exceeding a quarter
of an inch.

The entire plant is quite fibrous and has a hirsute surface. The color
varies from whitish to alutaceous and yellowish. It is not common with
us. Figure 375 represents one of the pilei showing the spines.

_Hydnum graveolens. Del._

FRAGRANT HYDNUM.

Graveolens means sweet-scented.

The pileus is coriaceous, thin, soft, not zoned, rugose, dark-brown,
brown within, margin becoming whitish. The stem is slender and the
spines are decurrent. The spines are short, gray.

The whole plant smells of melilot; even after it has been dried and kept
for years it does not lose this scent.

I found two specimens in Haynes's Hollow.

_Irpex. Fr._

Irpex, a harrow, so called from a fancied resemblance of its teeth to
the teeth of a harrow. It grows on wood; toothed from the first, the
teeth are connected at the base, firm, somewhat coriaceous, concrete
with the pileus, arranged in rows or like net-work. Irpex differs from
Hydnum in having the spines connected at the base and more blunt.

_Irpex carneus. Fr._

This plant, as its specific name indicates, resembles the
color of flesh. Reddish, effused, one to three inches long,
cartilaginous-gelatinous, membranaceous, adnate. Teeth obtuse
and awl-shaped, entire, united at the base. _Fries._

Found on the tulip-tree, hickory, and elm. September and October.

_Irpex lacteus. Fr._
