title: The Genus Pseudoleskeella (Bryophyta) In Russia

Molecular phylogenetic analysis found a quite separate position of P. tectorum and P. nervosa, while P. rupestris, P. catenulata and P. papillosa appeared to be rather closely related. Pseudoleskeella rupestris is an extremely variable species in Russia, comprised partly by plants with short double or forked costae in some leaves which makes difficult its differentiation from P. tectorum; such mo
