DNA barcode sequencing discovered the aecial host of Puccinia chunjiei .

The telial stage of was described in 2012 from a single specimen collected in China (DAOM 240982). This species is the closest relative of but differs in telial morphology on their grass hosts and in DNA sequences. As part of a DNA-barcoding project for rust herbarium specimens, collections of the aecial stage of on were processed. For one specimen, BPI 1103856, the ITS sequence matched that of and the aecial morphology differed from . An expanded description of is presented with photographs of the aecial stages of both species.
