The moss flora of Artvin Province (Ardanuc, Savsat, Borcka, Murgul, and Arhavi districts) in Turkey was studied between 2009 and 2011. A total of 167 moss taxa (belonging to 80 genera and 33 families) were recorded within the study area. Among these, 3 species [Dicranella schreberiana (Hedw.) Dixon, Dicranodontium asperulum (Mitt.) Broth., and Campylopus pyriformis (Schultz) Brid.] are new records from the investigated area for the moss flora of Turkey. The research area is located in the A4 and AS squares in the grid system adopted by Henderson in 1961. In the A5 grid-square 127 taxa were recorded as new records, and 1 taxon [Anomodon longifolius (Schleich. ex Brid.) Hartm.] was recorded for the second time in Turkey.
