SUMMARYA survey of the wood-inhabiting fungi occurring at three stations in the Saugatucket River in Rhode Island revealed a total of 59 species: 15 Ascomycetes, 36 Hyphomycetes, four Zygomycetes, and four Coelomycetes. These fungi were collected on both naturally occurring wood and submerged wood baits, during the period April to December 1974. The number of species collected was similar in spring and fall with a drop in numbers during August. There was a sharp rise in the number of species found in September following a period of heavy rainfall. Small variations were found in the number of species at each station. Discomycetes were more frequent at Station 1, an area of unpolluted water, than at Station 3, the area of highest pollution.
