=Boletus ferrugineus Frost [non Schaeffer]

Both pileus and stipe are deep reddish-brown, the hymenophore, at first white, becomes fleshy-pink, and the mild, white context stains pinkish-reddish when cut. A similar species is Tylopilus badiceps (Peck) A. H. Smith & Thiers, with paler brown colors in pileus and stipe, and usually beveled margin. The taste is also mild.
