Summary:ABSTRACT This study aimed to document the species of Euastrum (Desmidiaceae) in a subtropical stream adjacent to an important environmental protection area, the Parque Nacional do Iguaçu, in the extreme west of Paraná State, Brazil. For this purpose, monthly samplings of periphytic material associated to Eleocharis minima Kunth were performed in the period between August 2012 and July 2013. This taxonomic inventory allowed the identification of 12 taxa at specific and infraespecific level. Eight new occurrences were recorded for Paraná State: Euastrum attenuatum var. splendens, E. bidentatum var. bidentatum, E. cornubiense var. cornubiense, E. croasdaleae var. croasdaleae, E. denticulatum var. quadrifarium, E. didelta var. quadriceps, E. elegans var. elegans and E. evolutum var. incudiforme.
