Multigene phylogeny and morphology reveal three new species of isolated from diseased plant branches in Fengtai District, Beijing, China.

Members of include saprobes, endophytes and important plant pathogens, which are widely distributed on various wood hosts and have a wide global distribution. In this study, the species definitions were conducted, based on multigene phylogeny (ITS, , , and genes) and comparisons of morphological characters. A total of 22 representative isolates obtained from 21 specimens in Fengtai District of Beijing City were identified as seven species of , including four known species (, , , ) and three novel species (, , ). The results provide an understanding of the taxonomy of species associated with canker and dieback diseases in Fengtai District, Beijing, China.
