Two new polypores from tropical China, and renaming two species of Polyporus and Phellinus

Two new polypores, Inonotus canaricola sp. nov. and Skeletocutis substellae sp. nov., are described. Both of them were found in Hainan, tropical China. I. canaricola is distinct from other species in the genus by bearing a black cuticle at the upper surface, presence of hyphoid setae in the trama and hooked hymenial setae, and having yellowish brown and subglobose to globose basidiospores. S. substellae is very similar to S. stellae but differs from the latter by swollen skeletal hyphae in potassium hytrochloride (KOH) and smaller basidiospores. In addition, Polyporus rhododendri is renamed as P. taibaiensis, because the previous name was illegitimate. A new combination, Phellinus yunnanensis, is proposed.
