Campylopus flexuosus (Hedw.) Brid. (Dicranaceae), as suboceanic and disjunct cosmopolitan moss found in the Caucasian part of Turkey, is here reported for the first time from Turkey. A site description and illustrations of the Turkish specimens are briefly given together with notes on its diagnostic characteristics and ecology. This record complements our knowledge on the bryodiversity of the Eastern Black Sea region of Turkey and closes gaps in the hitherto known distributional range of this species.
