Abstract
Based on maximum growth temperatures, morphological characteristics and multilocus phylogenies (partial 18S and 28S, internal transcribed spacer regions of nuc rDNA and a fragment of an actin gene), Umbelopsis roseonana and U. versiformis are treated as heterotypic synonyms of U. nana, while the phylogenetically closely related U. dimorpha is retained as a separate species. Mortierella longicollis is reclassified as a new combination, U. longicollis. In addition, lectotypes and epitypes for the basionyms of U. longicollis and U. nana are designated here.
