Type speciesSammeyersia grandispora (Meyers) S.Y. Guo, E.B.G. Jones & K.L. Pang

NotesSammeyersia was introduced by Abdel-Wahab et al. (2017) to accommodate Sammeyersia grandispora which was earlier Lulworthia grandispora. Sammeyersia grandispora is identified by the length of the ascospores over 400 μm (Abdel-Wahab et al. 2017). Our new isolate groups with the S. grandispora isolates deposited in GenBank (Fig. 16). Therefore, based on both morphological and phylogenetic data we identified our new isolate as S. grandispora. Sammeyersia grandispora is illustred herein (Fig. 154).
