Bamboo is the largest member of the family , and these fast-growing plants have many beneficial ecological effects. Both mutualistic and pathogenic fungi associate with bamboo, however, only a limited number of such fungal species have been identified, and information concerning the diversity of fungi that parasitizes bamboo leaves is sparse.
Fungi were isolated from diseased leaves of bamboo from Fujian Province, China. Nucleotide sequences of four genetic loci were used for taxonomic and phylogenetic reconstruction. In addition, the morphological characteristics of fungal structures as well as growth parameters were characterized.
We report two new fungal species, one each within the and , both diverse genera that include saprophytes, endophytes, and pathogens. Based on combined morphological and phylogenetic analyses, including the nucleotide sequences of the internal transcribed spacer (ITS), the 28S large subunit of ribosomal RNA (LSU), the 18S small subunit of nuclear ribosomal RNA gene (SSU), the large subunit of RNA polymerase I (), and the translation elongation factor 1-α gene (α), the two new species described herein have been named as sp. nov., and sp. nov. Detailed descriptions and morphological features of the species are provided.
These data identify and describe new species within the and , expanding the diversity and distribution of fungi associating with bamboo.
竹子是禾本科中最大的成员，这些生长迅速的植物具有许多有益的生态效应。互利共生真菌和致病真菌都与竹子相关联，然而，仅鉴定出了有限数量的此类真菌物种，并且关于寄生于竹叶上的真菌多样性的信息稀少。
从中国福建省患病的竹叶中分离真菌。利用四个基因位点的核苷酸序列进行分类和系统发育重建。此外，还对真菌结构的形态特征以及生长参数进行了表征。
我们报告了两个新的真菌物种，分别属于 和 ，这两个属都包含腐生菌、内生菌和病原菌。基于形态学和系统发育分析的结合，包括内部转录间隔区（ITS）、核糖体RNA的28S大亚基（LSU）、核糖体RNA基因的18S小亚基（SSU）、RNA聚合酶I的大亚基（ ）以及翻译延伸因子1-α基因（α）的核苷酸序列，本文描述的两个新物种已被命名为 新种和 新种。提供了这些物种的详细描述和形态特征。
这些数据鉴定并描述了 和 中的新物种，扩大了与竹子相关联的真菌的多样性和分布范围。
