 Lucien Quélet placed the taxon in "Dictyopus" in 1886 and then "Rhodoporus" in 1888, but neither of these genera are recognised today, the former having been merged into "Boletus" and the latter into "Tylopilus".Genetic analysis published in 2013 shows that "T. felleus" and many (but not all) other members of "Tylopilus" form a "Tylopilus" clade within a larger group informally called anaxoboletus in the Boletineae.Other clades in the group include the porcini and "Strobilomyces" clades, as well as three other groups composed of members of various genera including "Xerocomus", "Xerocomellus" and "Boletus badius" and relatives.
