ABSTRACT. Recently collected specimens of poorly known Siberian taxa of Plagiothe­ciaceae were studied for DNA sequence data, nuclear ITS1-2 and chloroplastic trnL-F, and mophology. This study revealed that Bardunovia baicalensis and Myurella acuminata belong to one species which is better to classify in the genus Platydictya, as P. acuminata (Lindb. & Arnell) Ignatov, comb. nov. The Yakutian plants of Platydictya jungermannioides are also discussed and illustrated.
