SUMMARY A strain of Tetraspora gelatinosa was isolated from a field collection and a technique for measuring quantitatively the production of zoospores was devised. The method employed compound colonies grown on agar from zoospore suspensions. The effect of 3 temperatures on zoospore production was tested: no zoospores were produced by the colonies at 3 C; zoospores were produced at 11 and 23 C and the final yield of zoospores at the 2 temperatures was not significantly different. However, at 11 C the maximum density of zoospores produced, measured by cell count, occurred after IS hr, while the maximum density at 23 C occurred after 21 hr.
