Type examinations were conducted for 32 species of polypores described by E.J.H. Corner. The following new combinations are proposed: Antrodiella subligativa, Coriolopsis albobadia, C. suberosifusca, Datronia perstrata, D. sepiicolor, Fomitella malaysiana, Fomitopsis subvinosa, Microporus affinis-microloma, M. subvernicipes, Nigrofomes nigrivineus, Perenniporia rufidochmia, Polyporus polyporiformis, and Trichaptum molestum. The following species are accepted in the original genus: Trametes pallidilusor, the appropriate name for T. daedaleoides Corner (nom. illegit.), and T. rugosituba. Daedalea pseudodochmia was already combined with the proper genus. The following species are synonyms: Trametes microporoides and T. multiflabellata, synonyms of M. subvernicipes; T. papuasia, a synonym of Coriolopsis glabro-rigens; T. paxillosa, a synonym of Coriolopsis brunneoleuca; T. perpallida, a synonym of Skeletocutis nivea; T. primulina, a synonym of Coriolopsis sanguinaria; T. rigidiceps, a synonym of M. affinis-microloma; Trametes sublutea, a synonym of Fomitopsis spraguei; T. subincana and T. textulaminata, synonyms of D. pseudodochmia; and T. umbrinopallens, a synonym of T. lactinea. The following species are dubious because of the poor condition of specimens: T. tenacipora, T. turpis, and T. verticalis. No authentic specimens were traced for T. polyblastes, T. rubrigrisea, T. salina, T. sediliensis, and T. substrata. Descriptions and line drawings are given for the little-known species.
