B. brevipes is a disreputable, dirty, tramp-looking fungus, from which the collector would expect no good. Nevertheless, when it has had a good scrubbing it becomes respectable and is sweet, tender, good eating. When other species abound, it does not pay for the cleansing.
B. collini´tus Fr.—collino, to besmear. Pileus convex, even, becoming pale when the brown gluten separates. Flesh white. Tubes adnate, elongated, naked, the mouths two-parted, pallid, becoming yellow. Stem firm, often tapering downward, somewhat reticulate with appressed squamules, white, becoming brown.
Woods of pine or fir. North Carolina, Curtis; New England, Frost.
I have seen no specimens of this apparently rare species. It is said to be solitary in its mode of growth and to resemble B. luteus in size and color, but to be distinct from it by its ringless, dotless stem. Dr. Curtis records it as edible. Peck, Boleti of the U.S.
I found three specimens at Haddonfield, N.J., October, 1897, under scrub pines. Cap 2½ in. across, convex, gibbous; stem equal, 2½ in. long, ½ in. in diameter, slightly tapering at base. The two-parted mouths to the tubes were very distinct. The stems were tough, but the caps, washed and fried, were good.
B. di´chrous Ellis. Pileus convex, viscose, dull red. Flesh soft, dull, yellowish-white, changing to greenish-blue where wounded, finally yellow. Tubes subdepressed around the stem, large, unequal, straw-colored, changing color like the flesh where wounded. Stem thickened below, solid, covered with a red scaly coat, except at the yellow apex, yellow within. Spores elliptical, slightly bent at one end, 2µ long.
Pileus 2–3 in. broad. Stem 3 in. long, 6 lines thick.
Dry soil in oak and pine woods. New Jersey. Ellis.
I have seen no specimens of this species. From the description, its affinities appear to be with B. bicolor, but it is placed here because of its viscose pileus. Peck, Boleti of the U.S.
B. ba´dius Fr.—bay-brown. Pileus convex, even, soft, viscose or glutinous, shining when dry, tawny-chestnut. Flesh whitish, tinged with yellow, bluish next the tubes. Tubes large, angular, long, adnate or sinuate-depressed, whitish-yellow, becoming tinged with green. Stem subequal, even, solid, paler, brown-pruinate. Spores fusoid-oblong.
