Fungi play essential role in the soil especially in biodegradation of toxicants. This study investigated the soil-borne fungi diversity of a major waste dumpsite in Bayelsa State, Nigeria. Triplicate samples of soil were collected from 6 locations at 50 ft distance apart. The samples were analyzed following standard mycological processes. Results of the fungi population ranged from 6.70 x 103 to 7.27 x 104 CFU/g. Analysis of variance showed significant variations (p=0.017) in the density of the soil-borne fungi across the study locations There was, no statistical difference (p>0.05) in mean values across some locations. A total of 13 fungi genera were identified with Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger and Saccharomyces species constituting the predominant isolates with frequencies of 17.40%, 14.64%, 16.85% and 12.15%, respectively. Other isolates include Penicillium, Fusarium, Mucor, Rhizopus, Cryptococcus, Cladosporium, Pullularia, Alternaria, Microsporium, Candida and Trichoderma species. The interaction between species across study locations ranged from 55.56 to 90.00 with a similarity index above critical level of significance (50%). This indicates that isolates of the dumpsite are similar. Again, most of the isolates are opportunistic pathogens with disease causing propensity especially in immune-compromised individuals. Therefore, there is need for appropriate personal protective gear and appropriate measures when working on dumpsites.
