Abstract
30 genera and 77 species, in addition to 4 varieties were isolated from 25 samples of each of barley, wheat, maize and sorghum grains collected from different places in Egypt. The broadest spectrum of genera and species was recorded in wheat (25 genera and 59 species + 4 varieties) followed by barley (21 genera and 52 species + 2 varieties), sorghum (14 genera and 33 species + 2 varieties) and maize grains (11 genera and 29 species + 2 varieties). Aspergillus, Fusarium, Penicillium and Rhizopus were the most common genera in the four grains, except maize where Penicillium emerged in low frequency. Aspergillus was the main component of the fungal flora of the four grains and contributed 79–94.4% of the gross total count of fungi. From the preceding genera A. niger, A. flavus, A. fumigatus, F. oxysporum, P. chrysogenum, P. corylophilum, P. notatum and R. stolonifer were the most frequent.
