Holotypes of Daedalea vorax Harkness 1879, Polyporus piceinus Peck 1889 and Phellinus laricis Pilát 1972, and the sporophores of Phellinus pini (Brot.: Fr.) A. Ames and P. chrysoloma (Fr.) Donk were studied. Comparative studies showed these three holotypes are identical and represent a distinct polypore species. The oldest valid name is Daedalea vorax Harkness, and a new combination Phellinus vorax (Harkness) Černý comb. nov. is proposed.
