A revision of original material showed that Phellinus sulphurascens is a juvenile stage of Inonotus heinrichii (Pil.) Bond. & Sing. Both are also conspecific with the North American Poria weirii. A transfer of Poria weirii to the genus Inonotus is proposed. Modern interpretation of Polyporus rheades as Inonotus rheades matches its original description. Type material, ecology, and distribution are discussed.
