ABSTRACT

(Cryptogams of the Parque Estadual das Fontes do Ipiranga, São Paulo, São Paulo State, Brazil. Algae, 45: Bacillariophyceae (Naviculales: Brachysira)). The floristic survey of Brachysira Kützing (Naviculales) of the Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, São Paulo State, Brazil, resulted from the analysis of 31 permanent preparations of diatom material collected between years 1991 and 2017. The water and substrate samples (macrophytes and rocks) from lentic systems, streams and the hydrophytoterium were collected and subsequently were oxidized for analysis under light microscope. Nine species and one morphotype were identified from 15 diatom slides, of which four species are new records for Brazil (Brachysira cf. calcicola Lange-Bertalot, Brachysira frenguellii (Manguin) Lange-Bertalot & Moser, Brachysira huitotarum Vouilloud, Sala & Núñez-Avellaneda and Brachysira intermedia (Østrup) Lange-Bertalot). Brachysira subrostrata Lange-Bertalot was registered for the first time in the State of São Paulo.
