The genus Vaucheria (Xanthophyceae) in Russia: morphotaxonomic diversity and distribution

Abstract

During 2011–2020, the Vaucheria species of Russia have been studied in terms of morphotaxonomic diversity and regional distribution. Twenty-nine species and varieties were identified on the base of microscopical observation of 1230 fertile specimens. Of these, 15 species and varieties are reported for Russia for the first time. The regional Vaucheria diversity is differentiated by habitats, which differ in degree of humidity, as well as frequency of inundation.
