Resumo: | The biodiversity studies of planktic cyanobacteria started in 1997 with intensive collecting in different water bodies of São Paulo State. Due to the problems brougth by eutrophication and cyanobacterial blooms, the samplings were concentrated in reservoirs of Alto Tietê region that supply drinking water to millions of people. The samples were collected with 20 µm plankton net or Van Dorn's bottle. Part of each one was preserved in formaldehyde or lugol solution and part was isolated. The culture strains were kept in BG11 and/or AMS1 media. Based on natural and culture material, 26 species were identified belonging to the families Chroococcaceae (2 taxa), Merismopediaceae (12), Microcystaceae (7) and Synechococcaceae (5). Among these species, six are potentialy toxic: Aphanocapsa incerta (Lemmerm.) Cronberg &amp;amp; Komárek, Microcystis aeruginosa (Kütz.) Kütz., M. botrys Teiling, M. panniformis Komárek et al., M. wesenbergii (Komárek) Komárek, and Radiocystis fernandoi Komárek &amp;amp; Komár.-Legn. Bacularia and Coelosphaeriopsis are genera reported for the first time in Brazil.
