Type studies of the polypores described by E. J. H. Corner from Asia and West Pacific Areas III. Species described in Trichaptum, Albatrellus, Boletopsis, Diacanthodes, Elmerina, Fomitopsis and Gloeoporus

Twenty-seven species of polypores described by Corner were identified by type examinations. Corneroporus gen. nov. is proposed, typified by Boletopsis subcitrina. The following new combinations are proposed: Coriolopsis lacunosa, Corneroporus subcitrinus, Heterobasidion arbitrarium, Rigidoporus dimiticus, Skeletocutis basifusca, Tyromyces dolosus, T. friabilis, T. hispidus, T. subochraceus. The following names are accepted in the original genera: Trichaptum agglutinatum, T. suberosum, and Gloeoporus sulphureus. Gloeoporus carri was already combined with the proper genus. The following species are synonyms: Trichaptum ceraceicutis, T. favoloides, Diacanthodes griseus, Elmerina unguliformis, Gloeoporus nigrescens, G. papuanus, G. pendens, G. umbrinus, and G. vitellinus. Gloeoporus cremeoalbus belongs to a difficult complex and an allied species is cited. The following species are dubious because of their poor or sterile conditions: Trichaptum jackiae and Fomitopsis euosma. No authentic specimens were traced for Albatrellus borneensis and Gloeoporus similis. Descriptions and line drawings are given for the accepted species.
