B. sublu´teus Pk.—luteus, yellow. Pileus convex or nearly plane, viscid or glutinous when moist, often obscurely virgate-spotted, dingy-yellowish, inclining to rusty-brown. Flesh whitish, varying to dull-yellowish. Tubes plane or convex, adnate, small, subrotund, yellow becoming ochraceous. Stem equal, slender, pallid or yellowish, dotted both above and below the ring with reddish or brownish glandules; ring submembranous, glutinous, at first concealing the tubes, then generally collapsing and forming a narrow whitish or brownish band around the stem. Spores subfusiform, ochraceo-ferruginous, 8–10×4–5µ. Pileus 1.5–3 in. broad. Stem 1.5–2.5 in. long, 2–4 lines thick.
Sandy soil in pine woods. New York, Peck, Clinton; New England, Frost.
The species is closely related to B. luteus, from which it differs in its smaller size, more slender stem and glutinous collapsing veil. Peck, Boleti of the U.S.
Found at Waretown, N.J., 1887, under pines and in same locality as B. luteus, for which it can be readily mistaken. It is usually covered with adherent sand or pine needles. Its flesh is tender with a pleasant glutinosity. Flavor good.
B. fla´vidus Fr.—light yellowish. Pileus thin, gibbous, then plane, viscose, livid, yellowish. Flesh pallid. Tubes decurrent, with large angular compound mouths, dirty yellowish. Stem slender, subequal, pallid, sprinkled with fugacious glandules above the entirely viscose ring. Spores oblong-ellipsoid, straight, subhyaline, 8–10×3–4µ.
Pileus 1–2 in. broad. Stem 2–3 in. long, 2–3 lines thick.
Pine woods and swamps. Pennsylvania, Schweinitz; North Carolina, Curtis; New England, Frost; California, H. and M.; Rhode Island, Bennett.
Fries says that this species is more slender than its allies, and differs from them all in its merely glutinous veil. Peck, Boleti of the U.S.
Dr. Curtis, of North Carolina, places it among edible species.
Many specimens were found by the writer near Waretown and Haddonfield, N.J., and a few at Mt. Gretna, Pa. The stems are thin and slightly spreading at the top. They are hard. The caps are excellent.
