Diversidade de fungos zoospóricos da Reserva Biológica de Mogi Gua？u, estado de S？o Paulo, Brasil

two areas of cerrado ("a" and "b") at different preservation stages were selected at the "reserva biológica de mogi gua？u", s？o paulo state, to survey zoosporic fungi diversity. water and soil samples were collected during the rainy (january and october 2008) and dry seasons (april and july 2008), every three months, at six sampling sites in areas "a" and "b". 434 specimens were obtained using the multiple baiting technique with cellulosic, chitinous and keratinous substrates, which are specific for the isolation of aerobic, parasitic or saprobial fungi. 38 species were identified, belonging to blastocladiomycota, chytridiomycota and oomycota. of these, 31 species are cited for the reserve for the first time. the results increased our knowledge of the occurrence of the organisms from cerrado in s？o paulo state and brazil, complementing previous studies in the reserve.
