comb. nov. () for (≡ ) inferred from phylogenetic evidence.

(≡ ), known as the mulberry rust which is an anamorphic rust fungus forming only aecidioid uredinia, were found on in Ibaraki and Saitama Prefectures, Japan. Molecular phylogenetic analyses using the combined dataset of sequences from 28S and 18S of the nuclear ribosomal RNA gene and Cytochrome-c-oxidase subunit 3 of the mitochondrial DNA revealed that this anamorphic rust fungus was a member of the clade composed of the genus . Therefore, a new combination, is proposed for this species.
