摘　　要：通过形态特征与系统发育分析(LSU和ITS),报道了玛利亚霉属Mariannaea的1个新种和1个新记录种。新种沉水玛利亚霉Mariannaea submersa的主要形态特征为透明、分支状的分生孢子梗上带有3-6个环生瓶梗,产孢细胞烧瓶形至锥形,分子孢子为宽梭形至卵圆形,无隔膜,颜色透明且带有尖锐顶部和截断底部。链状玛利亚霉Mariannaea catenulata首次采集于淡水环境,同时也是首次报道于亚洲地区(泰国)。本研究进一步证明玛利亚霉属真菌在淡水环境中的高多样性。A new species and a new record of Mariannaea(Nectriaceae, Sordariomycetes) collected from freshwater habitats, are reported based on morphological characters and phylogenetic analyses of combined LSU and ITS sequence data. Mariannaea submersa sp. nov. is characterized by hyaline, septate, branched conidiophores with 3–6 verticillate phialides, flask-like to awl-shaped conidiogenous cells, and broadly fusiform to ovoid, aseptate, hyaline conidia with pointed tip and narrowly truncated base. Mariannaea catenulata is first collected from freshwater habitats and first collected from Asia(Thailand). This study further proves a high diversity of Mariannaea species in freshwater habitats.
