Sixty three species in addition to one variety belonging 25 fungal genera were recovered during this investigation. Three species of aquatic Hyphomycetes are new records to Egypt. The composition of water-borne fungi was basically similar to those of the washwater (phyllosphere) and plant part samples (phylloplane). No qualitative variations but quantitative differences were observed. Of the 17 identified zoosporic species, Dictyuchus sterilis, Pythium thalassium and P. intermedium were the commonest species. On glucose Czapek's agar medium the most frequent species in three substrates were members of Fusarium, Aspergillus and Penicillium. Some fungal species were isolated only from water samples and not from phyllosphere or phylloplane and vice versa. Aspergillus niger and A. flavus were the commonest species in water samples and phyllosphere whereas F. moniliforme was the prevalent species in phylloplane.
