Abstract

|
The distribution and occurrence of aquatic zoosporic and terrestrial fungi were investigated in 21 well waters in Assiut governorate, Egypt. Using a zoospore capture technique, 923 colonies of aquatic freshwater fungi were recovered from well waters, out of which 811 colonies reached sexual maturity. These colonies were assigned to 23 species which belong to 11 genera. The most common genera were Achlya, Saprolegnia and Dictyuchus. Using two types of media, 35 species in addition to 2 varieties of terrestrial fungi which belong to 18 genera were also recovered. The most frequent glucophilic genera (recovered on glucose-Czapek's agar at 28oC) were Aspergillus, Penicillium and Fusarium. The results obtained on cellulose-Czapek's agar at 2oC were basically similar to those on glucose agar and the most frequent genera were Aspergillus, Penicillium and Fusarium followed by Chaetomium and Cephalosporium.
