ABSTRACT. ITS sequences of taxonomically difficult complexes in the genus Dicranum, D. fuscescens-D. flexicaule and D. brevifolium-D. acutifolium-D. pseudacutifolium, are analyzed. Type specimens of D. pseudacutifolium are found to be poorly developed specimens of D. flexicaule and therefore the former name is synonymizedwith the latter. At the same time, several specimens previously identified as D. brevifolium were found to be in a separate clade; they also have morphological differences and are described as a new species, D. septentrionale sp. nova.
