Sažetak
Two new species of calcareous algae (Dasycladaceae) are described.One - Salpingoporella croatica n. sp. -is characterized by a clyindrical skeleton and undivided, phloiophorous to partly vesiculiferous rarnifications, arranged in whorls. The other species- Uragiella ragusinan.sp. - also has a cylindrical thallus and ramifications arranged in whorls. The shape of the ramifications, however, varies from nodular or tubercular to atypically pyriform and more rarely, to the Uragiellatype. The ramifications are often deformed, which is particularly visible in more distal tangential sections. Both species are found in the same sample which belongs, chronostratigraphically, to the Upper Dogger.
