During studies concerning the occurrence of some fungi and fungus-like organisms in the Biała River in Bialystok, forty-three species were established. Among 34 straminipilous fungi, the most common species were Achlya americana, A. debaryana, A. polyandra, Aphanomyces laevis, Dictyuchus monosporus, Pythium debaryanum, Saprolegnia ferax, and S. parasitica. New for the Polish fungal biota were Achlya ambisexualis, Calyptralegnia basraensis, and Achlya papillosa. Achlya crenulata, A. diffusa, A. flagellata, Aphanomyces stellatus, and Pythium afertile were considered rare. Physical and chemical analysis showed that the water of Biała River in Białystok had a high content of ammonium nitrogen and phosphate, reflecting poor cleanliness.

Excretion into the environment of dissolved organic matter produced during photosynthesis is a characteristic phenomenon for several species of aquatic macrophytes (Wetzel 1969 a, b). Several of these substances are imbibed by heterotrophic microorganisms and may also inhibit the growth of other hydrobionts. An examination of the interactions between macrophytes and aquatic fungi showed that during the growing period (spring, summer and autumn), relationships between these organisms change. At the beginning of the growth period, the number of species of aquatic fungi rose in the presence eight macrophytes; during the summer there was a decrease in the number of fungi observed; while in the autumn (end of the growing season) there was an inhibitive influence of macrophytes on the growth of aquatic fungi, which was higher in eutrophic water. This inhibitive influence depends probably on the storage of any secondary compounds during aging of several macrophytes, which inhibit the growth of several species of fungi and fungus-like organisms.

Straminipilous organisms and fungus species on dead fragments of 25 taxa of wetland plants from three water bodies were investigated. A total of 219 fungal taxa, including 85 straminipilous organisms and 134 fungus species were recorded. The largest number of straminipilous organisms and fungus species occurred on fragments of Lathyrus palustre and Rorippa amphibia (45 and 44 species respectively), the fewest on Calla palustris (20). The most common species were Chytridium xylophilum (on 23 plants), Pythium rostratum (on 15), Pithomyces obscuriseptatus (on all plants), Trinacrium subtile (on 17) and Titaea (Tetracladium) maxilliformis (on 16). The larger numbers of species were recorded in running water (Jaroszówka Spring, Supraśl River, 124 and 122 respectively), with fewest (106) in stagnant water at Dojlidy Pond. Thirty-one taxa were recorded for the first time from Poland.

The authors investigated aquatic fungi and chromistan organisms (fungus-like organisms) growing on dead fragments of 7 species of floating-leaved plants (Limnanthemum nymphoides, Nuphar luteum, Nuphar pumilum, Nymphaea alba, Nymphaea candida, Polygonum amphibium f. natans and Potamogeton natans) in the water from three limnological and trophical different water bodies (spring, river and pond). They identified 106 species including 42 chromistan organisms and 64 fungus species, found on the fragments. A number of chromistan organisms and fungus species (Catenomyces persicinus, Nowakowskiella profusa, Polyphagus parasiticus, Rhipidium americanum, Rhipidium interrupta, Rhipidium partenosporum, Sporodina grandis, Endophragmiella latifusiformia, Pseudocercospora manuensis and Saprochaete ramosissima) are recorded as new to Polish waters.
