在调查云南次生林植物根系内生真菌的过程中，从云南高山栎（Quercus cocciferoides Hand.）马兹和软叶白蜡Fraxinus malacophylla Hemsl.该新种的特征是具有椭圆形或倒卵球形的分生孢子细胞，顶端有数个扁平的小孢子囊，分生孢子为双锥状，无隔，光滑，淡褐色，具透明至近透明的赤道横带和顶端管状附属物。系统发育分析的内部转录间隔区和LSU rRNA基因的组合序列证实了它的新种Beltrania属内的地位。本文对该新种进行了描述和图解，并提供了Beltransiais属种的分类检索表。
During a survey of endophytic fungi in plant roots in secondary forests in Yunnan, China, a novel ascomyceteous taxon,Beltrania sinensis, was isolated fromQuercus cocciferoidesHand.-Mazz. andFraxinus malacophyllaHemsl. This novel species is characterized by having oval or obovoid conidiogenous cells with several apical, flat-tipped denticles, and biconic, aseptate, smooth, pale brown conidia with a hyaline to subhyaline equatorial transverse band and apical tubular appendage. Phylogenetic analysis of the combined sequences of the internal transcribed spacer and the LSU rRNA gene confirmed its novel species status within the genusBeltrania. Here, the novel species is described and illustrated, and a taxonomic key to species in the genusBeltraniais provided.
