Abstract
A new species of Mucor, isolated from the surface of Lycorma delicatula collected at Cheongyang in the Chungnam Province of Korea, is described and compared with morphologically similar taxa. The phylogenetic analysis of the internal transcribed spacer (ITS) and the large subunit (28S) rDNA sequences revealed that this isolate is closely related to M. orantomantidis and M. guilliermondii. However, the new isolate differs from those by having larger sporangia (24.5–125 × 23.5–120 µm), rhizoid-like structures, and production of secondary sporangia from vesicles outside of the original sporangium. Here, this novel fungal taxon is proposed as Mucor cheongyangensis sp. nov.
