In this study, three deadwood-dependent liverwort species (Calypogeia suecica (Arnell & J.Perss.) Müll. Frib., Crossocalyx hellerianus (Nees ex Lindenb.) Meyl. and Scapania apiculata Spruce) are reported upon from forests of North-western Anatolia for the first time for Turkey and Southwest Asia. The results concluded an increasing number of Scapania species to 17, Calypogeia species to six for these areas. Also, Crossocalyx is a new genus record for Turkey and Southwest Asia. All three new records are approximately at the southernmost limit of these species' distribution of Western Asia; also records of C. hellerianus and S. apiculata are at the southern limit of their Mediterranean distribution. Morphological descriptions, microphotographs, ecological aspects, distinctive taxonomical features, and Turkish conservation suggestions of the new records are presented. In addition, some remarkable deadwood-dependent bryophyte species (Buxbaumia viridis (Moug. ex Lam. & DC.) Brid. ex Moug. & Nestl., Fuscocephaloziopsis lunulifolia (Dumort.) Váňa & L.Söderstr. and Lophozia guttulata (Lindb. & Arnell) A.Evans.) in Turkey are discussed.
