The Catenella caespitosa (Withering) L.M. Irvine community at two stations on the Slovenian coast of the northern Adriatic Sea was sampled monthly during 2002. The flora consisted of 18 species: seven Chlorophyceae, five Rhodophyceae, two Fucophyceae, and four Cyanobacteria. The diversity index indicated low community complexity at both stations (0.8 at station A and 0.5 at station B) and confirmed the identification of the zonation of this community. A new sub-association of the upper mid-littoral zone Catenelletosum caespitosa, included in the Fucetum virsoidis Pignatti 1962 association, is described by the synecological method.
