ECOLOGICAL SPECIFICITY OF SOME AQUATIC HYPHOMYCETES IN JAPAN

Abstract

The conditions under which the aquatic Hyphomycetes are distributed were studied in some Japanese lakes and rivers. There are two groups of aquatic fungi i.e. 1) the fungi inhabiting in running water and 2) that of in standing water. Marked differences are seen according to the differences in lake type. Tricladium gracile var. oxyphilum and Anguillospora longissima are distributed mostly in the acidotrophic lakes. Varicosporium elodeae and Tricladium gracile are the only species in the dystrophic lakes. On the other hand, Tetrachaetum elegans, Articulospora teraclodia and Lemonniera aquatica are the main fungi in the harmonic lakes.
