  The phylogeny of the Calliergon-Loeskypnum-Straminergon-Warnstorfia clade is reconstructed based on nuclear and chloroplast sequence data, and morphology from an earlier study, but with the addition of two chloroplast markers that contributed 23 (of a total of 113) or 13 (95) characters with or without insertions and deletions coded as informative, respectively. Based on the total data set Calliergon, which appeared as a grade in the earlier study, is now resolved as monophyletic. The separation of the autoicous and dioicous Warnstorfia species in two separate lineages was indicated by the earlier study and the support for this is even higher in the present study. The dioicous species are therefore all transferred to the genus Sarmentypnum Tuom. & T. J. Kop., which was earlier described to accomodate S. sarmentosum (Wahlenb.) Tuom. & T. J. Kop. The new combinations Sarmentypnum exannulatum (Schimp.) Hedenäs, S. luipichense (R. S. Williams) Hedenäs, S. procerum (Renauld & Arnell) Hedenäs, S. pseudosarmentosum (Cardot & Thér.) Hedenäs, S. trichophyllum (Warnst.) Hedenäs, and S. tundrae (Arnell) Hedenäs, are made.
