Toadstools, mushrooms, fungi, edible and poisonous; one thousand American fungi

=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. The species which constitute this tribe are easily distinguished from all others by the sulphur-colored pulverulence which coats the pileus and stem like a universal veil. They appear thus far to be peculiar to this country. Though strongly resembling each other in the tribal character they are very diverse in other respects. One species, by its viscidity, connects with the preceding tribe; another by its differently colored tube mouths is related to the Luridi; and the third is peculiar in its ligneous habitat.
