Boletus edulis is distinguished from other members of the bolete group by a combination of characters: substantial size, a smooth to wrinkled brown to reddish-brown cap surface, drab white pores becoming yellowish olive in age, a usually club-shape stipe with distinctive white reticulations at the apex, mild taste, and absence of color changes. A close relative is Boletus regineus (Queen bolete) which differs in having a darker cap with a whitish wash when young, and occurs with mixed hardwoods as opposed to pines.
