Abstract

RESUMO O levantamento florístico das Surirellales (Bacillariophyceae) do PEFI, Parque Estadual das Fontes do Ipiranga, São Paulo, SP, Brasil resultou da análise de 28 unidades amostrais. As amostras planctônicas foram coletadas com auxílio de rede de plâncton e as de perifíton pela raspagem de substratos duros ou coleta de macrófitas aquáticas submersas. O material foi oxidado e analisado aos microscópios de luz. Dois gêneros e 15 espécies foram identificados, dos quais nove são novas citações para o PEFI e são: Stenopterobia delicatissima (F.W. Lewis) L.A. Brébisson ex H. van Heurck, S. pelagica F. Hustedt, S. planctonica D. Metzeltin & H. Lange-Bertalot, S. curvula (W. Smith) K. Kramer, Surirella angusta F.T. Kützing, S. guatimalensis C.G. Ehrenberg, S. stalagma M.H. Hohn & J. Hellerman, S. splendida (C.G. Ehrenberg) F.T. Kützing e S. tenera W. Gregory.ABSTRACT Floristic survey of order Surirellales (Bacillariophyceae) in the Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP, Brazil was based on the analysis of 28 sampling units. Plankton samples were collected with a plankton net and periphyton by scraping hard substrates and/or gathering aquatic macrophytes. Samples were oxidized and analyzed under a light microscope. Two genera and 15 species were identified. Nine taxa are cited for the first time for the PEFI area: Stenopterobia delicatissima (F.W. Lewis) L.A. Brébisson ex H. van Heurck, S. pelagica F. Hustedt, S. planctonica D. Metzeltin & H. Lange-Bertalot, S. curvula (W. Smith) K. Kramer, Surirella angusta F.T. Kützing, S. guatimalensis C.G. Ehrenberg, S. stalagma M.H. Hohn & J.
