Based on our morphological review and phylogenetic analysis, Cyathodium tuberosum was recorded from Beijing City, representing the northernmost distribution record of the genus worldwide. Given the morphological differences in the genus Cyathodium and the phylogenetic results generated in this study, subg. Metacyathodium S.C.Srivast. & R.Dixit ex T.X.Zheng was formally validated. |
