Diversity and Pathogenicity of Six Species from in China.

Walnut ( L.) is cultivated extensively in China for its substantial economic potential as a woody oil species. However, many diseases caused by greatly affect the health of trees.

Updating the Species Diversity of Pestalotioid Fungi: Four New Species of and .

Pestalotioid fungi are associated with a wide variety of plants around the world as pathogens, endophytes, and saprobes. In this study, diseased leaves and branches of plants were collected from Guizhou and Sichuan in China. Here, the fungal isolates were identified based on a phylogenetic analysis of the internal transcribed spacer region (ITS), the translation elongation factor 1-alpha (-) and the beta-tubulin () of ribosomal DNA, and the morphological characteristics.

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 (, , ).
