Abstract
Samples were collected from three rivers and streams of varying physical and chemical characteristics. The samples were examined for aquatic Phycomycetes. The fungi were found in all samples collected. The filamentous forms were abundant in all three rivers. However, the unicellular forms were infrequently encountered or absent in the eutrophic river but very common in the oligotrophic situations. Samples collected immediately below the introduction of the effluent from an Army ammunition plant showed a greatly reduced flora of aquatic Phycomycetes. Achlya flagellata, a Rhizidium sp. and a Phlyctochytrium sp. were isolated from natural collections and their responses in terms of growth and reproduction to zinc, mannitol, cyanide, and surfactants were observed.
