The diversity of fungi and fungus-like organisms on fruits of 251 plant taxa from three water reservoirs in Poland was investigated. A total of 348 taxa, including 142 fungal species, 203 straminipilous organisms and three plasmodiophorids were recorded. The largest number of fungal species and straminipilous organisms occurred on fruits of Rhamnus alaternus (35 species), Crataegus azarolus (34), Arum maculatum (28), Morus alba (26) and Mahonia japonica (24). The most common species were Saprolegnia ferax (on fruits of 116 species), Rhipidium interruptum (72), R. americanum (70), Aphanomyces irregularis (66), Pythium rostratum (57), Saprolegnia glomerata (57) and Aphanomyces laevis (56). The greatest numbers of species was recorded from running waters at Cypisek Spring (246) and the smallest (209) from stagnant waters at Komosa Lake, i.e. 56 and 42 exclusive for each of the water bodies, respectively. Aphanomyces polysporus, Gracea waterhouseae, Pythium horinouchiense, Pythium pachycaule and Saprolegnia multispora are first noted for Polish waters.
