Type studies of the polypores described by E.J.H. Corner from Asia and West Pacific Areas. V. Species described in Tyromyces (2)

Identification of 33 species of polypores described by Corner in 1989 and 1992 were made by type examinations. The following new combinations are proposed: Antrodia multipapillata, Antrodiella negligenda, Elmerina substuppea, Fomitopsis ostreiformis, F. scorteus, F. singularis, Hyphodontia ovispora, Oligoporus subfragilis, Oxyporus rufipusillus, Perenniporia permacilenta, Polyporus oncospermatis, Rigidoporus malayanus, and Trichaptum perpusillum. The following names are accepted in the original genus: Tyromyces levis, T. mediocris, T. mollicaseus, T. nemorosus, and T. stenomitis. The following species are synonyms: Tyromyces miser, a synonym of Dichomitus eucalypti; T. montanus, a synonym of T. mollicaseus; T. perskeletalis, a synonym of Fomitopsis ostreiformis; T. polycystes, a synonym of Hyphodontia arguta; T. roseipileus, a synonym of T. incarnatus; and T. subfibrillosus, a synonym of T. mollicaseus. Final determination was not made for T. rubrifuscescens, which may be conspecific or allied with Elmerina substuppea. Tyromyces sinapicolor belongs to Corticiaceae sensu lato with a nonporoid hymenophore. Tyromyces ochraceicarneus may be also a member of Corticiaceae sensu lato, but final determination was not made. The following species are dubious because of the poor or sterile conditions of their type specimens: Tyromyces ochraceivinosus, T. pinguidus, T. pusillicaesius, T. rhodomelon, T. rubricarneus, and T. descendens. No authentic specimens were traced for T. pulviniformis and T. rufipileatus. Descriptions and line drawings are given for little-known species.
