Further studies on aquatic fungi in the River Narew within the Narew National Park.

Zoosporic and conidial fungi species and environmental factors in 10 various sites of River Narew in the Narew National Park were studied. Samples of water were collected in autumn 1999 and spring 2000 for hydrochemical analysis and the order to determine the number of fungal species. Buckwheat-seeds, hemp-seeds, cellophane and snake exuviae were used as bait during the exposure in laboratory. 198 lower aquatic fungus species were found in various sites of River Narew. 13 species were recorded for the first time from Poland.
