A guide for species identification of representatives of the genus Ceramium (Roth, 1797) along the Turkish coast is elaborated in this study. Some of the samples used in this study were collected from our previous field studies. However, inappropriate and missing samples in the Herbarium were collected again. The samples were also studied from the personal herbarium of Huseyin ERDUGAN. Twenty-six species of genus Ceramium Roth were found and identified along the shores of Turkey, with Ceramium camouii Dawson 1944, being a new record from the Mediterranean. In this study, a catalog based on the morphological and anatomical characteristics of genus Ceramium Roth found on the shores of Turkey is described.
