Description
Summary:Members of (Pucciniaceae, Pucciniales) are known as plant pathogens worldwide, which are characterized by their morphology, host association, and molecular data of various genes. In the present study, 10 specimens of were collected from four herbaceous plants ( , and ) in China and identified based on morphology and phylogeny. As a result, 10 samples represent four undescribed species of , viz., , and , spp. nov. is characterized by its smooth teliospores with thickened apex. represents the first species inhabiting the host and is distinguished from the other species by its telia and uredinia surrounded by the epidermis. from differs from the other species on the host genus by the telia that have epidermis and teliospores with sparsely irregular granulated protrusions. is characterized by its teliospore surface with fishnet ornamentation and urediniospores without prominent caps. All of the new species are described and illustrated in this study.
