Genetic relationships between 27 Orthotrichum species of the subgenera Orthotrichum and Pulchella were reconstructed using the internal transcribed spacer regions 1 and 2, the chloroplast trnH‐psbA region, and intron–exon splice junction (ISJ) and inter‐simple sequence repeats (ISSR) markers. A phylogenetic analysis did not reflect the current division of the subgenus Pulchella into the sections Diaphana , Pulchella , and Rivularia . Species of the section Rivularia did not form a monophyletic group, and the only markers that indicated the distinctness of the section Pulchella were ISJ and ISSR. The most genetically diverse section was Diaphana , whose species were divided into several clades. The only proper phylogenetic unit was the subgenus Orthotrichum . The applied markers revealed the process of cryptic speciation in species of both subgenera.
