Investigations on the Joint Occurrence of Anabaena spiroides Klebahn and Hyphomycetes in Various Types of Water Bodies

The authors investigated the influence of the cyanobacterium Anabaena spiroides on the occurrence of aquatic Hyphomycetes in the water of five water bodies of different trophy. The presence of cyanobacteria in the water of all five waters reduced the number of fungi species from 29 to 10. Such species as Angulospora aquatica and Mirandina corticola were found both in control samples and with cyanobacterium from all five waters examined.
