Abstract
During the spring and summer of 1979, 48 species of geofungi and several sterile, unidentified fungi were isolated from two off-shore stations on the Bay of Fundy, Canada. Isolations were made from subsurface water and surface slicks on 6 agar media including one containing hexadecane, and from subsurface water baited with hemp seeds. Numbers of fungi were 10 to 100 times higher than those reported for other offshore stations and similar to those reported for a saltmarsh outflow. Species isolated during a high freshwater flow largely corresponded to a typical soil flora. Species isolated during a reduced freshwater flow were either marine in character or noted for association with area littoral seaweeds. Three fungi (Cladosporium cladosporioides, Trichoderma viride, and Gliocladium rosium) were tested for growth on media of increasing salinity. Growth was measured by dry weight production, pH drop and glucose used in liquid culture. C. cladosporioides showed responses typical of a marine fungus, T. viride of a terrestrial fungus and G. roseum was intermediate. The results are discussed in relation to the role of geofungi in the sea.
