ABSTRACT
Paper is the taxonomic survey of the Mesotaeniaceae (Zygnemaphyceae, Zygnemales) present in the PEFI, Parque Estadual das Fontes do Ipiranga lacustrine systems. The examined material included periphyton and plankton from different aquatic systems within the PEFI, and the revision of all material cited for the Park deposited in the Scientific State Herbarium “Maria Eneyda P. Kauffmann Fidalgo” (SP). Five species were identified, which are distributed in three genera (Cylindrocystis, Mesotaenium, and Netrium). IAG Pond was the system presenting the highest species richness (three taxa) probably due to its oligotrophic characteristics.
