Cellulose-decomposing fungi of barley grains in Egypt

100 species and 2 varieties of A. nidulans which belong to 35 genera were identified from 40 samples of barley collected from different places in Upper Egypt. Two methods of isolation were used: the grain-and the dilution plate. The spectrum of fungal genera and species collected by the former (35 genera, 96 species+1 variety) was broader than by the latter method (28 genera, 76 species+1 variety). Nine genera were of high occurrence (represented in more than 50% of the samples) namely, Aspergillus, Penicillium, Fusarium, Alternaria, Chaetomium, Cladosporium, Humicola, Drechslera and Myrothecium. The most frequent species were A. fumigatus, A. niger, A. flavus, A. sydowii, F. oxysporum, F. moniliforme, A. alternata, M. verrucaria, P. funiculosum, P. corylophilum, P. duclauxi, C. herbarum, C. globosum, D. spicifera and H. grisea. Several fungi such as Chaetomium, Humicola, Altemaria, Drechslera, Stachybotrys, Myrothecium, Pénicillium corylophilum and P. funiculosum were far more frequently recovered on cellulose than on glucose agar.
