Abstract

An investigation was carried out on the aquatic fungi developing on seeds of some plants in 4 types of water bodies (Cypisek Spring, Bug River, Dojlidy Pond and Komosa Lake) of Podlasie Province, Poland. The bait method was used to isolate the fungi. Seventy-four aquatic fungal species were found on seeds of three species of plants: Cannabis sativa (59), Fagopyrum esculentum (55) and Vicia sativa (44) in 4 types of water bodies. The mould species belonged to Blastocladiales (5), Chytridiales (6), Monoblepharidales (1), Hyphochytriales (1), Lagenidiales (5), Leptomitales (4), Peronosporales (14), Saprolegniales (37) and Plasmodiophorales (1). The most common were Achlya americana, Achlya polyandra, Aphanomyces laevis, Pythium rostratum, Saprolegnia ferax and Saprolegnia parasitica. The following phytopathogens were determined: Achlya racemosa, Phytophthora infestans, Pythium butleri, Pythium debaryanum and Pythium myriotylum.
