long, 3 to 6 lines thick, rigid, fibrous, striate, equal, reddish or pale yellow. This species is variable. We found one where the flesh was white, another where the tubes changed finally to green, and one that had an olive tint in the pileus.
BOLETUS ILLUDENS = deceiving.
The Deceiving Boletus.
Cap yellow or olive brown, 3 inches broad, plane, dry, marked with areoles, that is, the surface is broken up into little areas or patches. Flesh thick, white, red under cuticle. Tubes greenish-yellow, turning dark green, adnato-decurrent, that is, broadly attached to the stem and running down it, ⅛ inch long. Stem 2½ inches long, stuffed with brownish fibres, reticulated near apex, paler color than cap, curved.
BOLETUS PACHYPUS = thick.
The Thick-stemmed Boletus.
Cap tan color, 4 to 8 inches broad, convex, somewhat covered with long, soft hairs pressed closely to surface, subtomentose; flesh thick, whitish, changing slightly to blue. Tubes rather long, depressed around the stem, mouths
round, pale yellow, at length tinged with green. Stem 2 to 4 inches long, thick, firm, reticulated, at first ovate, bulbous, then lengthened, equal, tinted pale yellow and red. The stem in the specimen was ¼ inch thick, swelling from apex downward, but it often measures 2 inches in thickness. This Boletus is considered poisonous.
BOLETUS SUBTOMENTOSUS = almost velvety.
The Yellow-cracked Boletus.
Cap dark brown, 1 to 4 inches broad, convex or nearly plane, soft, dry, covered with soft, weak, appressed hairs, almost olivaceous, of the same color beneath the cuticle, often marked with cracks and divided into little patches; flesh white or pallid. Tubes adnate, or depressed around the stem, yellow, mouths large, angular. Stem 1 to 2½ inches long, 2 to 5 lines thick, stout, somewhat ribbed, or scurfy, with minute dots. The cap varies in color, it may be yellowish-brown. We found the dark brown species growing on decaying wood, in pine woods, during the month of September.
BOLETUS PIPERATUS = peppery.
The Peppery Boletus.
Cap reddish-brown or ochraceous, 1 to 3 inches broad, convex or nearly plane, smooth, slightly viscid when moist, flesh white or yellowish, taste acrid, peppery. Tubes long, large, unequal, plane or convex, adnate or nearly decurrent, reddish, ferruginous. Stem 1½ to 3 inches long, 2 to 4 lines thick, slender, almost equal, tawny yellow; at the base a bright yellow. The cap in our specimen was marked with cracks and patches, and the margin obtuse. The stem was rather curved, and the same color as the cap. Flesh yellow. Tubes a dark-reddish, decided color, which makes it a striking-looking mushroom. Taste peppery.
