The lichen flora of the western part of the Black Sea region is still very poorly known, although it is known as one of the most interesting and species rich biogeographic elements in Turkey with some strongly oceanic floristic elements (John 1996). In nine papers referring to lichens in the province of Kastamonu (Czeczott 1939; John 1992, 1996; Motyka 1936; Ozdemir Tiirk 1997; Szatala 1927; Yildiz & Yurdakulol 1998a, 1998b; Zeybek et al. 1993) only 50 species are considered. The following list is restricted to the 66 taxa new to Kastamonu province. Five species are reported for the first time from Turkey: Bacidia circumspecta, B. friesiana, Diplotomma nivale, D. venustum, Schismatomma pericleum. The paper is a further contribution towards a checklist of the Mediterranean lichen flora (Nimis 1996).
