Communities of corticolous cyanobacteria present in tropical regions show significant complexity and diversity. However, few works direct efforts to understand the composition of these communities, which ends up being underexplored. In Brazil, studies focusing on corticolous cyanoflora are scarce, with most of them done with material from the country's Southeast region, but revealing a unique diversity, with many new genera and species described. Thus, the study aimed to carry out a taxonomic survey on corticolous cyanobacteria in the urban area of Dois Irmãos Park, PE, Brazil. For this, sampling was carried out during the dry (11/2020) and rainy seasons (03/2021), in three similar trees of Clitoria fairchildiana R.A.Howard. The samples were gathered in an area of 25 cm2 using spatulas and stored in paper bags for taxonomic analyses, which were performed under optical microscopy with the production of 5-7 slides per sample. It was possible to identify 21 taxa: four identified at the genus level, one in affinis, three in conferatur, and 13 species. Of these, three species are new citations for Brazil, four species, and one genus for northeastern Brazil. The number of taxa found, and the number of new citations brought in this work show a great diversity in the northeast region that is still little explored, and additional work is needed to understand the biodiversity of cyanobacteria in this region.Downloads
