Twenty‐five identified and 3 unidentified species in addition to one variety belonging to ten genera of aquatic fungi were recovered from 20 surface water samples collected from different aquatic sites in Tübingen region (Baden‐Württemberg, Germany) during July‐September 1992 using sesame seeds as baiting substances. Three genera were of high occurrence; Saprolegnia (8 species), Aqualinderella (one species) and Pythium (6 species) and two genera namely Achlya (2 species) and Dictyuchus (one species) were of moderate occurrence. Allomyces (3 species + one variety) and Aphanomyces (one species) were of low occurrence whereas Olpidiopsis, Phytophthora, Pythiopsis and Thraustotheca were of rare occurrence (one species each). Saprolegnia contributed the broadest spectrum of species (8 species). The richest water samples in Saprolegnia species (7 species) and the aquatic fungal species (15 species) was number one which collected from the river Neckar while this group of fungi disappeared completely in sample number (16). It seems that the most effective factor in the occurrence and distribution of this group of fungi during this study was the water temperature.
