Abstract: Nineteen species were recovered belonging to 9 genera of aquatic fungi in addition to unidentified species of Aphanomyces, Pythium and Saprolegnia. These species were isolated from surface water and submerged mud samples collected from canal polluted with industrial effluents of Kima factory for fertilizers and River Nile during the period from January to December 1996 at Aswan region, using baiting technique of sesame seeds at 22+1 oC. Pythium, Nowakowskiella and Saprolegnia contributed the broadest spectra of species. Pythium (5 identified in addition to unidentified species), Nowakowskiella (4 species), Saprolegnia (3 identified and unidentified species), whereas the other aquatic fungal genera of the narrowest spectra of species.
