The ecological studies of aquatic fungi were carried out in the mesotrophic Lake Yamanakako from August to November in 1957. 1. The zoospores of aquatic fungi showed considerable variation in amounts, with the maximum in autumn and the minimum in summer and late autumn. 2. The seasonal fluctuation of the fungi differed according to species, i.e. Aphanomyces sp. flourished in summer, and the genus Saprolegnia in autumn. Pythium sp. was obtained both in summer and autumn. 3. The zoospores of aquatic fungi were distributed uniformly from the surface to the lake bottom in autumn, while they were seen only in the epilimnion in summer. 4. The aquatic fungi of the bottom deposit were rich in autumn in number of species. Pythium sp. was the preponderant member in every season. 5. The standing crop of the fungi differed between the Main and the Hirano basins according to diversity of their limnological natures.
