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.

Phylogeny and taxonomy of three species of (Pucciniales) from East Asia.

Three species of the rust fungus genus , and , have been reported in East Asia. Although their morphological characteristics and life cycles have been investigated, their phylogenetic positions have not been clarified sufficiently. Phylogenetic analysis showed that these three species were included into Zaghouaniaceae of Pucciniales.
