Morphological and molecular methods were combined to identify the pathogen of leaf spot of Codonopsis pilosula.Traditional cultural methods of plant pathology were used to test the cultural characteristics and a phylogenic tree was built through rDNA-internal transcribed spacer(ITS)sequencing.Pycnidia were spherical or sub-spherical,53.8-76.6 μm×40.3-62.7 μm in diameter;conidia were hyaline,needle,one to four septate,15.3-38.8 μm×0.9-1.2 μm in diameter.Phylogenic analysis of ITS confirmed that the pathogen ...
