The presence of this species in Chongqing extends its distribution range from Japan to China. That the current disjunct distributions of M. nipponensis in China and Japan are attributed to relatively recent long-distance dispersals or human introductions remains an open question. The macromorphology of the Chinese collection is in accordance with the descriptions of typical M. nipponensis, which was originally described from Japan (Clowez et al. 2022). Microscopically, the ascospores of Chinese collections are smaller than those reported from Japan, (18 -) 20–23.5 (- 24) × (10.5 -) 11.5–12.5 (- 13) µm, but asci are larger than those from Japan by Clowez et al. (2022). The multi-gene sequences of M. nipponensis generated from the Chinese collections are closely related to that generated from the Japan collection, and the phylogenetic position of this species is well-settled (Fig. 7).</p></div>	https://treatment.plazi.org/id/51F9C11651125B98A13423F26346081E	Public Domain	No known copyright restrictions apply.
