Two rare Scapania species, S. calcicola and S. glaucocephala, are recorded for the first time for Turkey during bryofloristic studies in the Black Sea region, north of Turkey. The record of S. glaucocephala is new to Southwest Asia and to the Mediterranean bryoflora and located at the southern limit of its range. Morphological descriptions and microphotographs of Turkish specimens, data on their distinctive features, ecology and distributions are provided.

In this study, the bryophyte flora of İğneada Floodplain Forest National Park (Kırklareli-Demirköy) and Acarlar Floodplain Forest (Sakarya-Karasu) in Turkey were investigated in 2016–2017. Here, we report Bryum gemmiferum R. Wilczek & Demaret from İğneada Floodplain Forest National Park in Turkey. In addition, we report Atrichum crispum (James) Sull from both İğneada and Acarlar Floodplain Forest in Turkey. Atrichum crispum is also a new record for Asia continent. Illustrations, location in Turkey and comparisons with morphologically similar taxa were given.

The bryophyte flora of Karacabey (Bursa) Floodplain Forest in Turkey was investigated in 2017. Here, we report Weissia multicapsularis (Sm.) Mitt. from forest. This globally important moss species is a new record for Turkey and the continent of Asia. Illustrations, details of the location in Turkey and comparisons with morphologically similar taxa are provided.

The bryophyte flora of Acarlar Lake (Sakarya-Karasu), Karacabey Floodplain Forests (Bursa) and Samanlı Mountains (Sakarya-Akyazı) was studied in Turkey between 2016-2017. As a result of these bryofloristic studies, we determined for the first-time records of Dicranella staphylina from three different localities in Turkey. Site descriptions, illustrations, diagnostic characters and comparisons with morphologically similar taxa are presented.
