B. subsanguin´eus Pk.—sub and sanguineus, bloody. (Plate [CXVI], fig. 4, p. 420.) Pileus convex or slightly depressed in the center, glabrous, viscid, bright-red or scarlet. Flesh thick, firm but flexible, white, slowly changing to a pale brownish-lilac on exposure to the air, taste slightly bitter. Tubes very short, 2–4 mm. long, adnate, but often separating from the stem with the expansion of the pileus, reddish, the mouths minute, stuffed at first, pinkish, then brownish-yellow, changing to a light-brown where wounded. Stem short, thick, uneven, often tapering downward, streaked with red, pale-yellow at the top, white at the base, marked at the top by the decurrent walls of the tubes.
Pileus 2.5–10 cm. broad. Stem 2.5–5 cm. long, 2–4 cm. thick.
Solitary, gregarious or cespitose. Under beech trees. West Philadelphia, Pa. August. C. McIlvaine.
This is a very showy species, easily recognized by its bright-red viscid pileus and its short, thick and uneven or somewhat lacunose stem. It is closely related to the European B. sanguineus With., from which it is separated by its minute tubes, its uneven stem and the brownish hues assumed where wounded.
The spore characters of this and the four succeeding species are unknown, but the other characters are quite distinctive and apparently sufficient for the recognition of the species. The descriptions have been derived from colored figures and other data furnished by Mr. McIlvaine, who says all are edible. Peck, Bull. Torrey Bot. Club, No. 27.
When slowly stewed for thirty minutes, there is no better Boletus.
Pulverulenti.
Pileus clothed with a yellow dust or a yellow powdery down. Stem more or less yellow powdered, neither bulbous nor distinctly reticulated.
