03BE87B55203413FD6AD9695519EFA41.taxon	discussion	Note: — Calcarisporium yuanyangense was isolated from O. nutans and was different from the host reported in previous studies. Calcarisporium yuanyangense was identified as a unique species based on both morphological characteristics and phylogenetic analysis; both demonstrate that it was distinct from other recognized species in the genus Calcarisporium. Phylogenetic analysis based on five genes showed strong support (BP = 100 % and PP = 100 %) with being an independent branch. Calcarisporium yuanyangense and C. arbuscula were similar in conidia shape, but the conidia of C. yuanyangense (6.33 – 9.68 × 1.87 – 2.63 μm) were larger and had a higher length / width ratio than those of C. arbuscula (Table 2).	en	Zhu, Juye, Tang, Dexiang, Liu, Zuoheng, Luo, Lijun, Yu, Hong (2023): Calcarisporium yuanyangense sp. nov.
