ABSTRACT
Twelve identified and three unidentified species representing five genera of zoosporic fungi were recovered from forty samples of accumulated rainfall water which were collected from Abha city, southwestern region in Saudi Arabia using Sesame seeds baiting technique at 20 ± 2 ° C. Allomyces anomulus. Aqualinderella fermentans and Pythium thalassium were the most dominant species of zoosporic fungi. A total of forty three species in addition to one variety which belong to nineteen genera of terrestrial fungi were isolated from forty samples of accumulated rainfall water on both glucose-and cellulose-Czapek’s Dox agar media at 28 ° C. Glucose Czapek’s Dox agar medium was somewhat richest in the isolated species of terrestrial fungi compared with cellulose Czapek’s Dox agar medium. Most of the recoverable genera and species of terrestrial fungi were similar on both of isolation media in spite of some species were isolated only once on one isolation medium. The most dominant terrestrial fungi taxa on both isolation media were: Aspergilliis niger: Rhizopus rhizopodiformis, A. flavus and Cladospormm cladosporoides.
