olivaceous, then somewhat viscous, sooty. The flesh is yellow,
changing to blue when wounded. Tubes free, yellow, becoming greenish,
their mouths round, vermilion, becoming orange. The stem is stout,
vermilion, somewhat orange at the top, reticulate or punctuate. The
spores are greenish-gray, 15x9u.

The lurid Boletus, though pleasant to the taste, is reputed very
poisonous. Boletus rubeolarius, Pers., having a short, bulbous, scarcely
reticulated stem, is regarded as a variety of this species. The
red-stemmed Boletus, B. erythropus, Pers., is also indicated by Fries as
a variety of luridus. It will be seen on the right in Figure 309. It is
smaller than B. luridus, has a brown or reddish-brown pileus and a
slender cylindrical stem, not reticulated but dotted with squamules.
_Peck_, Boleti of the U. S. The plant is quite abundant in our woods.
Found in July and August.

_Boletus castaneus. Bull._

THE CHESTNUT BOLETUS. EDIBLE.

[Illustration: Figure 310.--Boletus castaneus. One-half natural size.]

[Illustration: Figure 311.--Boletus castaneus.]

Castaneus, pertaining to a chestnut. The pileus is dry, convex, then
expanded, minutely velvety; cinnamon or reddish-brown, from one to three
inches in diameter; the flesh white, not changing when bruised, cap
frequently turned upward.

The tube-surface is white, becoming yellow, tubes small and short, free
from the stem.

The stem is equal or tapering upward, colored and clothed like the cap,
short and not always straight; when young it is spongy in the center but
becomes hollow with age. The spores are pale-yellow, oval or broadly
elliptical, which is a feature to distinguish the species.

I found a number of specimens in James Dunlap's woods, near Chillicothe,
Ohio. A great majority seemed to be attacked by the parasitic fungi,
Sepedonium chrysospermum.

The caps are very fine eating. Care should be taken to use only young
specimens. Found in open woods from June to September.

_Boletus satanus. Lenz._

SATANIC BOLETUS.

Pileus convex, smooth, somewhat gluey, brownish-yellow or whitish; flesh
whitish, becoming reddish or violaceous where wounded. Tubes free,
yellow, their mouths bright red, becoming orange-colored with age. The
stem thick, ovate-ventricose, marked above with red reticulations.

Hamilton Gibson and Captain McIlvaine seem to give his Satanic majesty a
good reputation, but I would say "Be cautious." His looks always
