Abstract

Fungi imperfecti were cultured from water and bottom sediment samples collected at four locations of Utah Lake. These study sites included: (a) The mouth of Provo River, the largest fresh-water tributary entering Utah Lake, (b) Mud Lake, a large shallow area known for its high nitrogen content, (c) the entrance of the Spanish Fork River into the lake, a large fresh-water tributary containing wastes from industry and agricultural enterprises, (d) Jordan River, the only natural outlet of Utah Lake. One hundred and thirty-eight species of fungi imperfecti were identified. A total of 89 species were isolated from the Spanish Fork River, 107 species from Mud Lake, 82 species from the Provo River, and 60 species from the Jordan River Outlet. Species that were restricted to a particular area included, 16 from the Spanish Fork River, 17 species from Mud Lake, 7 species from the Provo River and 6 from the Jordan River Outlet. The total number of fungi cultured from each station was in a direct relationship to the percent organic matter present. Seven species of Aspergillus which are potential human and animal pathogens were identified. Potential plant pathogenic fungi identified included 22 species.
