Figure 302.—Boletus griseus. Two-thirds natural size.
Griseus means gray. The pileus is broadly convex, firm, dry, almost smooth, gray or grayish black. The flesh is whitish or gray.
The tubes are attached to the stem and slightly depressed around the stem, nearly plane, their mouths being small, nearly round, white or whitish.
The stem is slightly unequal, tapering downward, distinctly reticulated, whitish or yellowish, sometimes reddish toward the base. The spores are ochraceous-brown, 10–14×4–5µ. Peck.
This plant, with us, grows singly and it is infrequently found. I have found it always in beech woods along Ralston's Run. It is found in August and September.
