通过形态学观察和系统发育分析，对我国北方柳属杨柳溃疡病病原菌进行了鉴定。它们被鉴定为四种：C.长喙虫属新种，C. nivea，C. chrysosperma和杨树腐烂病菌（Valsa populina）。喙状胞孢菌是甘肃省杯柳上的一个新喙型种。它在形态上区别于其他Cytospora种，其子实体具有单室和刺状喙。从内转录间隔区（ITS）获得的分子证据也表明，C。喙状体代表胞孢属内的一个独特谱系。这是我国首次发现的C.柳上的妮维雅
Fungal specimens from Salix causing willow Cytospora canker in northern China were evaluated through morphological observation and phylogenetic analysis. They were identified as four species - C. rostrata sp. nov., C. nivea, C. chrysosperma, and Valsa populina. Cytospora rostrata is a new beaked species parasitizing Salix cupularis in Gansu Province, China. It is morphologically distinguished from other Cytospora species by its fruiting bodies with a single locule and a thorn-like beak. Molecular evidence obtained from the internal transcribed spacer (ITS) region also suggests that C. rostrata represents a distinct lineage within Cytospora. This is the first Chinese record of C. nivea on Salix.
