Diversity of (pestalotioid fungi) from in China.

() is an important ornamental and medicinal plant genus worldwide, with several species being cultivated in China. Members of (pestalotioid fungi) are globally distributed and include endophytes, saprobes but also plant pathogens, infecting a broad range of host plants on which they can cause important plant diseases. Although several species were recorded to inhabit spp., the taxa occurring on remain largely unresolved. In this study, a total of 295 diseased samples were collected from branches, fruits, leaves and spines of eight species (. , . , . , . , . , . , . and . ) in Gansu, Henan, Hunan, Qinghai, Shaanxi Provinces and the Ningxia Autonomous Region of China. Subsequently 126 strains were obtained and identified based on comparisons of DNA sequence data. Based on these results 15 species residing in six genera of were delineated, including four known species (, . , and . ) and 11 new species described here as , , . , , , . , . , . , , , and . . This study also represents the first report of . , . and . on . The overall data revealed that was the most prevalent genus, followed by , while . and . were the two most prevalent species. Analysis of abundance on species and plant organs revealed that spines of . had the highest species diversity. : Peng C, Crous PW, Jiang N, et al. 2022.
