Resumo: Massive growth of Spirogyra Link was observed in multispecific banks of aquatic macrophytes in the Baía River, Upper Paraná River floodplain, in August 2019. In the laboratory and under optical microscopy, reproductive stages (conjugation) were observed in the collected specimens, which made it possible to determine the species taxonomically as Spirogyra maxima (Hassall) Wittrock. This species is characterized by the wide variation in the size of vegetative cells, spiral plastids arranged in up to nine ribbons and with small pyrenoids. Zygospores have lenticular morphology of the reticulated wall. The occurrence of this species represents a new citation for the Upper Paraná River floodplain.

Em laboratório e sob microscopia óptica foi possível observar estágios reprodutivos (conjugação) dos espécimes coletados, o que possibilitou determinar taxonomicamente a espécie como Spirogyra maxima (Hassall) Wittrock. Essa espécie é caracterizada pela ampla variação de tamanho de suas células vegetativas, plastos espiralados dispostos em até nove fitas e com pequenos pirenoides. Os zigósporos possuem morfologia lenticular de parede reticulada. A ocorrência desta espécie representa uma nova citação para a planície de inundação do Alto Rio Paraná.Iheringia.
