Abstract

Umbelopsis changbaiensis is described as a new species of the genus Umbelopsis, Umbelopsidaceae, Mucorales. It was isolated from forest soil mix in Changbai Mountain, Jilin Province, China. The new species is distinct from all the previously described species mainly in colony color, branching type of sporangiophores, and shape and size of columellae. Maximum growth temperatures and phylogenetic analyses of the internal transcribed spacer (ITS1–5.8S–ITS2 region), partial large subunit (28S D1–D3 region) of rDNA, and partial actin gene (act-1) support the morphological result. The closest ally of U. changbaiensis is U. vinacea whose basionym Mortierella vinacea was published by Dixon-Stewart in 1932 without any type material indicated. The only figure provided in the protologue is designated here as the lectotype of M. vinacea and a dry culture from its authentic strain CBS 212.32 is designated here as an epitype for this lectotype. Descriptions and illustrations are provided for both U. changbaiensis and U. vinacea.
