Based on examination of herbarium specimen that was previously misidentified as Selaginella helvetica (L.) Spring, we report the first voucher-based record of S. kraussiana (Kunze) A. Braun from the eastern Carpathian Mountains in West Ukraine. A morphological comparison of S. kraussiana with S. helvetica and S. selaginoides occurring in this region is given. Selaginella kraussiana differs from them in habit, vegetative leaves and strobili structure.
