abstract = {Dicranum is a large (c. 90 species) and taxonomically complex genus of mosses. Circumscriptions and relationships of many Dicranum species remain ambiguous due to the absence of a worldwide revision and comprehensive molecular phylogenetic analyses. In the present study, species circumscriptions of morphologically similar, and possibly closely related, Dicranum species (D. scoparium, D. bonjeanii, D. fuscescens, D. howellii, D. cf. japonicum, D. majus, D. nipponense, and D. spadiceum) are analysed based on chloroplast (rpoB, trnH-psbA, trnL-trnF, rps4-trnT, rps19-rpl2) and nuclear ribosomal ITS sequences. Contrary to their morphological resemblance and the presence of intergrading forms, all analysed species are molecularly separated and form well supported clades in the molecular phylogenetic reconstructions. The identity of two North American D. cf. scoparium specimens, which may represent a formerly separate taxon or a ?pseudo-cryptic? species, remains to be tested. Dicranum bonjeanii, D. howellii, D. cf. japonicum, D. nipponense, and D. scoparium (all sect. Dicranum) can be comprised as D. scoparium species complex, while D. majus (sect. Dicranum) and species currently considered to belong to other sections (D. fuscescens and D. spadiceum) are separated from this complex. Further supraspecific relationships remain largely unresolved based on the present molecular data. The significance of morphological characters for species identification are discussed. It is concluded that a combined morpho-molecular approach allows clear species circumscriptions in Dicranum, which is a promising result for the study of other taxonomically difficult complexes of closely related species in bryophytes.}
