, in woods and
in open places. One variety was of a yellowish tan color, Var.
alutaceus, in another the flesh changed slightly to pinkish when
wounded, Var. mutabilis (Peck). (Edible.)

+BOLETUS CASTANEUS = chestnut.+
+The Chestnut Boletus.+

+Cap+ a chestnut color, brown or reddish brown, 1 1/2 to 3 inches broad,
convex, nearly plane or depressed, firm, even, dry, minutely velvety
(tomentose), flesh white. +Tubes+ free, short, small, white, becoming
yellow. +Stem+ 1 to 2 1/2 inches long, 3 to 5 lines thick, equal or
tapering upward, even, stuffed or hollow, colored like the cap. This is
one of the prettiest of the Boleti. The bright chestnut color of the
pileus forms a contrast with the white tubes, and makes it striking in
appearance. We found it on several occasions, as it is common in woods.
There are differences of opinion in regard to its being edible.

+BOLETUS CHRYSENTERON = golden.+
+The Golden Flesh Boletus.+

+Cap+ dark brown or reddish-brown, 1 to 3 inches broad, convex or plane,
soft, covered with woolly scales, sometimes marked with lines, flesh
yellow, red beneath the cuticle, often slowly changing to blue when
wounded, mouths large, angular, unequal. +Stem+ 1 to 3 inches 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, 1/8 inch long. +Stem+ 2 1/2 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 1
