摘要： Introduction Bamboo is the largest member of the family Poaceae, 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.Methods 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.Results We report two new fungal species, one each within the Didymosphaeriaceae and Magnaporthaceae, 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 (rpb1), and the translation elongation factor 1-alpha gene (tef1-alpha), the two new species described herein have been named as Bifusisporella magnum sp. nov., and Letendraea bambusae sp. nov. Detailed descriptions and morphological features of the species are provided.Discussion These data identify and describe new species within the Didymosphaeriaceae and Magnaporthaceae, expanding the diversity and distribution of fungi associating with bamboo.
