A study of Chytridiales diversity was based on water and soil samples collected monthly from June/2005 to June/2006 in the Serra da Cantareira State Park, São Paulo State. The isolation of these fungi was carried out in the laboratory treating the water and soil samples by the multiple baiting technique with cellulosic, chitinous and keratinous substrates. Nineteen species were identified with four new citations for Brazil, Cladochytrium setigerum Karling, Diplophlyctis intestina (Schenk) J. Schröt, Rhizophydium macroporosum Karling and Solutoparies pythii Whiffen ex W.H. Blackw. & Powell. Septochytrium willoughbyi Dogma is recorded for the first time in São Paulo State.
