Notes on rust fungi in China 1. Autoecious life cycle of Puccinia tatarinovii on Prenanthes

During investigations of rust fungi in Jilin Province, northeast China, aecial and telial stages were observed on Prenanthes tatarinowii in different seasons. The telial stage was identified as Puccinia tatarinovii by morphological observations. Life cycle connection between aecial and telial stages was clarified by field observations and molecular data. Morphology of the spermogonial and aecial stages is described based on specimens connected to telial stage. Lectotype and epitype specimens are designated.
