| Algae and Cyanobacteria can colonize a wide variety of terrestrial environments and the assemblages from aerophytic habitats are very poorly known. During the survey of aerophytic algal and cyanobacterial communities in forest fragments in northwestern São Paulo state, six cyanobacteria populations could not be identified at species level and, after morphological and metrical analysis, proved to be new morphotypes to Science. Four belong to the genus Aphanothece (A. excentrica, A. coacervata, A. densa and A. vaginata), one to Phormidium (P. arboricola) and one to Hapalosiphon (H.santannae). This study presents the description, comparison and proposition of the new morphospecies and improves taxonomic knowledge of the diversity of the group. |

| Cyanobacteria are common in aquatic environments but are also well-adapted to terrestrial habitats where they are represented by a diversified flora. The present study aimed to contribute to our taxonomic knowledge of terrestrial cyanobacteria by way of a floristic survey of the main components of corticolous communities found in seasonal semideciduous forest fragments. Samples of visible growths of Cyanobacteria, algae, and bryophytes found on tree bark were randomly collected and their taxonomies examined. Eighteen species of Cyanobacteria were found belonging to the genera Aphanothece, Chroococcus, Lyngbya, Phormidium, Porphyrosiphon, Hapalosiphon, Hassalia, Nostoc, Scytonema, and Stigonema. Many genera and species observed in the present work have been... |
