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.
