Podosphaera, is described and illustrated on Pyrus ussuriensis in China. P. paracurvispora differs from P. clandestina and P. leucotricha which are common causal agents of Pyrus powdery mildew in having crescent-shaped ascospores, and differs from P. curvispora, endemic in Japan on Sorbus spp., in having much broader pale brown ascospores. Phylogenetic analyses based on rDNA ITS and partial 28S rDNA sequences clearly support P. paracurvispora as species of its own, genetically well separated from the others. The morphological characteristics and phylogenetic results strongly suggest that the fungus is a new, undescribed species. } }
