Type studies of the polypores described by E.J.H. Corner from Asia and West Pacific Areas. VI. Species described in Tyromyces (3), Cristelloporia, Grifola, Hapalopilus, Heterobasidion, Ischnoderma, Loweporus, and Stecchericium

Identifications were made by type examinations for 27 species of polypores described by Corner. Roseofavolus gen. nov. is proposed, typified by Grifola eos. The following new combinations are proposed: Amylocystis unicolor, Antrodiella xanthochroa, Cristelloporia pahangensis, C. rutilantiformis, Roseofavolus eos, Tyromyces armeniacus, T. olivascens, and Wrightoporia solomonensis. Hapalopilus rubescens is accepted in the original genus. The following species were already combined with the proper genus: Stecchericium gyroporum and S. trametoides. The following species are synonyms: Tyromyces sublamellatus, a synonym of Abortiporus roseus; T. subradiatus, a synonym of Daedaleopsis conchiformis; T. subroseiporus, a synonym of Fomitopsis scorteus; T. subtrimiticus, a synonym of Fomitopsis spraguei; T. sulphureiceps, a synonym of Antrodiella flava; and Loweporus corticicola, a synonym of C. rutilantiformis. The following species are dubious because of their poor or sterile conditions: Cristelloporia trimitica, Loweporus castaneus, Tyromyces subrubescens, and T. tristaniae. No authentic specimens were traced for Ischnoderma brunneipurpureum, I. friabile, I. solomonense, Loweporus ochraceicinctus, L. pileoliferus, Stecchericium trimiticum, and Tyromyces xanthophaes. Descriptions and line drawings are given for little-known species.
