Algae in phytotelmata from Caatinga: first record of the genus Rhopalosolen Fott (Chlorophyta) for Brazil

Abstract

The first record of the genus Rhopalosolen Fott (Chlorophyta) for Brazil is presented here. Taxonomic studies on phytotelm algae are, in general, scarce, but especially are so in semi-arid regions such as the Caatinga. Here, we sampled 60 bromeliads in the Itaberaba’s municipality, Bahia state, and we identified Rhopalosolen cylindricus, a green algae species not previously recorded for Brazil. Additionally, our data provide an expansion on the known distribution of the species and their morphological and reproductive aspects as well as microhabitat conditions and frequency of occurrence.
