Abstract
Mycoflora of 40 soil samples collected from cultivated and desert soils, exposed to cement dust were studied. Ten species belonging to 7 genera of zoosporic fungi, in addition to Dactylella rhompospora (aquatic hyphomycetes) were recovered from cultivated and desert soils, using baiting technique. Pythium debaryanum and Dictyuchus sterilis were the commonest species. Seventy-one species in addition to two varieties, which belong to 34 genera were collected from 20 samples of each of cultivated (20 genera and 45 species + 1 var.) and desert (31 genera and 61 species + 2 var.) soils, on glucose-agar medium. On cellulose-agar medium, fifty-six species and 2 varieties representing 26 genera were collected from 20 samples of each of cultivated (24 genera and 40 species + 2 var.) and desert (20 genera and 40 species + 2 var.) soils. Aspergillus, Penicillium and Emericella were the most frequent genera in the studied soils on both media.
