The fungal composition of domestic wastes and waste stabilisation pond water samples from two geographically distinct localities—Dharwad and Gulbarga in Karnataka State was studied. Fungi of wastewaters and stabilisation pond at Dharwad comprised of 13 species belonging to 8 genera and 16 species belonging to 11 genera respectively and that of wastewaters at Gulbarga comprised of 19 species belonging to 12 genera. Species belonging to 9 genera were recorded commonly in both the localities. Statistical analysis of the results indicated thatAspergillus flavus, Aspergillus niger, Penicillium oxalicum andTrichosporon sp. occurred in all the samples with high percentage of occurrence and high degree of consistency. Occurrence of some of the organisms commonly in two different environments (from the point of organic loading)—wastewaters and stabilisation pond-reflects upon their lymaphilic nature.
