Abstract: Mycoflora from the soil of Kotri barrage at down stream was investigated at three locations viz., Right Bank, Centre and Left Bank from July 2005 to May 2006. Thirty samples were collected from surface, 10, 20, 30 and 50cm depth. The fungi were isolated by using soil dilution and soil plate method. Out of 90 strains of fungi isolated, 21 species of Aspergillus viz., A. niger (21.07), A. flavus (18.26), A. ocharaceus (17.28), A. wentii (7.47), A. flavus oryzae (7.85), A. fumigatus (8.49), A. sulphureus (2.29), A. ustus (3.48), A. violaceofuscus (1.82), A. flavipes (2.97), A. terreus (0.80), A. clavatus (0.72), A. restrictus (0.93), A. versicolor (0.55), A. candidus (1.35), A. nidulans (0.38), A. citrisporus (0.04), A. granulosus (1.95), A. sparsus (0.55), A. elegans (0.50), A. giganteus (1.14) were identified. Greater number of species were isolated on soil plate method than on dilution plate method. Higher number of species were recovered from Right bank as compared to left bank while in centre isolates were in low frequency.
