ABSTRACT. A phylogenetic analysis of ITS1-2 sequences from 117 specimens of Schistidium from Eurasia and North America revealed several new taxa within the genus. Schistidium sibiricum Ignatova & H.H. Blom, S. obscurum H.H. Blom, Köckinger & Ignatova, S. tenuinerve Ignatova & H.H. Blom, S. bakalinii Ignatova & H.H. Blom, S. echinatum Ignatova & H.H. Blom and S. succulentum Ignatova & H.H. Blom are described as new for science. Three new combinations are made: S. canadense (Dupr.) Ignatova & H.H. Blom, S. abrupticostatum (Bryhn) Ignatova & H.H. Blom and S. konoi (Broth.) Ignatova & H.H. Blom. Illustrations are provided for new species. A preliminary key for the identification of Schistidium species known in Russia is given.
