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

_Peck_, Boleti of the U.S. =B. con´icus= Rav.—conical. =Pileus= convex or _subconical_, clothed with bundled appressed _yellowish flocci_. =Flesh= white, unchangeable, tasteless. =Tubes= ventricose, flesh-colored, becoming darker from the spores, the mouths small, angular, slightly fringed. =Stem= glabrous, tapering upward, pale-yellow. =Spores= fusiform, subferruginous. =Pileus= 1–2 in. broad. =Stem= 2 in. long, 6 lines thick. Damp pine woods. South Carolina, _Ravenel_. The species is compared to Boletus scaber, from which it differs in its smaller tubes and smooth stem, and from both this and B. albellus it differs in the color of the tubes and in the yellowish flocci of the pileus. I have seen no specimens, but on account of the color of the tubes I have placed the species with the Hyporhodii. _Peck_, Boleti of the U.S. =B. gra´cilis= Pk.—slender. (Plate CXIV, fig. 1, p. 414.) =Pileus= convex, glabrous or minutely tomentose, rarely squamulose, ochraceous-brown, tawny-brown or reddish-brown. =Flesh= white. =Tubes= plane or convex, depressed around the stem, nearly free, whitish, becoming pale flesh-colored, their mouths subrotund. =Stem= _long, slender_, equal or slightly tapering upward, pruinose or minutely branny, even or marked by slender elevated anastomosing lines which form long narrow reticulations. =Spores= subferruginous, 12.5–17.5×5–6µ. Var. _l[oe]´vipes_. =Stem= even. =Pileus= 1–2 in. broad. =Stem= 3–5 in. long, 2–4 lines thick. Woods. New York, _Peck_; New England, _Frost_; Ohio, _Morgan_. The slender habit separates this species from all the others here included in this tribe. Its spores are not a clear incarnate in color, but incline to dull-ferruginous, and by this character this and the preceding species connect this tribe with Versipelles. In color B. gracilis resembles some forms of B. felleus, but in size, habit and color of spores it is easily distinct. The tomentum of the pileus sometimes breaks into tufts or squamules. This is Boletus vinaceus, Frost MS. _Peck_, Boleti of the U.S. B. gracilis, var. lævipes, was found by the writer in Woodland Cemetery, West Philadelphia, August, 1897, and at Mt. Gretna, Pa., September,
