A number of inedible boletes are superficially similar in appearance but lack one or more of the key characteristics. The edible Boletus fibrillosus
differs in that the cap is dark brown, velvety/fibrous, the stem is brown except at the yellow apex, and the pores on the underside are yellow at all stages. The edible Boletus regineus
differs in having an almost black, burnt-looking cap.
