Integrative analysis of expanded sampling of Pallaviciniales revealed the heterogeneity of Moerckiaceae. The new family Cordaeaceae Mamontov, Konstant., Vilnet & Bakalin is described based on morphology and molecular phylogenetic data. It includes one genus Cordaea Nees with two species, C. flotoviana (= Moerckia flotoviana), the type of the genus, and C. erimona (Steph.) Mamontov, Konstant., Vilnet & Bakalin comb. nov. Descriptions and illustrations of all species of the order known from Russia including newly reported Pallavicinia subciliata and provisional P. levieri are provided. Identification key for Pallaviciniales known from Russia and adjacent areas is given.
