New aerophytic morphospecies of Cyanobacteria from tropical forest fragments in northwestern São Paulo state, Brazil Acta Botanica
Lemes-da-Silva,Nadia Martins; Branco,Luis Henrique Zanini; Necchi-Júnior,Orlando.
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.

Corticolous green algae from tropical forest remnants in the northwest region of São Paulo State, Brazil Rev. Bras. Bot.
Lemes-Da-Silva,Nadia Martins; Branco,Luis Henrique Zanini; Necchi-Júnior,Orlando.
The algae inhabit a wide variety of terrestrial environments and substrates; however the taxonomic knowledge for tropical regions is still scarce. This survey was conducted in ten forest remnants in São Paulo State where visible growths of algae and bryophytes were collected and studied for the main algal components of the communities. Results reveal the occurrence of nine species of green algae, distributed through the class Trebouxiophyceae (one species), Charophyceae (one species) and Ulvophyceae (seven species). Desmococcus olivaceus (Persoon ex Archerson) J. R. Laundon and Printzina effusa (Krempelhüber) Thompson & Wujek are new records for Brazil. The most frequent organisms found in the areas pertain to Trentepohliales that is mainly...
