Sesquicillium shanghaiense (Zhi Yuan Zhang, Y. F. Han & Z. Q. Liang) S. C. He, K. D. Hyde & Jayaward, [as ‘ shanghaiensis’] comb. nov. Basionym. Clonostachys shanghaiensis Zhi Yuan Zhang, Y. F. Han & Z. Q. Liang, MycoKeys 98: 198 (2023). Holotype. HMAS 351878. Description and illustration. Zhang et al. (2023). Notes. Clonostachys shanghaiensis was established by Zhang et al. (2023), based on ITS and tub 2 sequence data (HMAS 351878). Clonostachys shanghaiensis clustered as a sister clade to C. rossmaniae (95 % MLB, 0.99 BYPP) (Zhang et al. 2023). In this study, phylogenetic analysis showed that Clonostachys shanghaiensis formed a successive sister clade with S. phyllophila, S. saulensis, and S. candelabrum (Fig. 1). It is worth noting that S. phyllophila, S. saulense, and S. candelabrum were renamed by Zhao et al. (2023) as C. phyllophila (Schroers 2001), C. saulensis (Lechat et al. 2020), C. candelabrum (Schroers 2001) and C. chuyangsinensis (Wang et al. 2023) based on morphology and phylogenetic analysis. Therefore, based on phylogenetic analysis, we propose C. shanghaiensis as a synonym of S. shanghaiense.
