Species of include a diverse array of plant pathogens as well as endophytic fungi. Members of this genus have been frequently collected from the family Betulaceae (birches) in Europe and North America. Little, however, if known concerning the distribution of and/or their potential as pathogens of other plant hosts.
Fungi were noted and isolated from diseased leaves of (Chinese fringe flower) and (tea) in Fujian Province, China. Genomic DNA was extracted from fungal isolates and the nucleotide sequences of four loci were determined and sued to construct phylogenetic trees. Morphological characteristics of fungal structures were determined via microscopic analyses.
Four strains and two new species of were isolated from infected leaves of and in Fujian Province, China. Based on morphology and a multi-gene phylogeny of the internal transcribed spacer regions with the intervening 5.8S nrRNA gene (ITS), the 28S large subunit of nuclear ribosomal RNA (LSU), the second largest subunit of RNA polymerase II (RPB2), and the translation elongation factor 1-α gene (TEF1-α), sp. nov. and sp. nov. were identified and described herein. Detailed descriptions, illustrations, and a key to the known species of are provided.
These data identify new species of , expanding the potential range and distribution of these dark septate fungi. The developed keys provide a reference source for further characterization of these fungi.
[该属真菌]包括多种植物病原体以及内生真菌。该属成员在欧洲和北美常从桦木科（桦树）中采集到。然而，关于[该属真菌]的分布和/或其作为其他植物宿主病原体的潜力却知之甚少。
在中国福建省，从[檵木]和[茶树]的病叶中发现并分离出真菌。从真菌分离物中提取基因组DNA，测定四个基因座的核苷酸序列，并用于构建系统发育树。通过显微镜分析确定真菌结构的形态特征。
从中国福建省的[檵木]和[茶树]感染叶片中分离出四株[该属真菌]和两个新物种。基于形态学以及内部转录间隔区与间隔的5.8S nrRNA基因（ITS）、核糖体RNA的28S大亚基（LSU）、RNA聚合酶II的第二大亚基（RPB2）和翻译延伸因子1-α基因（TEF1-α）的多基因系统发育分析，本文鉴定并描述了[新物种名称1]和[新物种名称2]。提供了详细描述、插图以及[该属已知物种]的检索表。
这些数据鉴定出了[该属真菌]的新物种，扩大了这些暗隔真菌的潜在范围和分布。所编制的检索表为进一步鉴定这些真菌提供了参考来源。
