Zoosporic fungi in the ice of some water reservoirs

Abstract

The presence of 65 zoosporic fungi species was noted in the water obtained from melting ice from five water (3 ponds and 2 rivers). In the water of the all basins the number of zoosporic fungus species decreases along with the increasing chemical loading (more eutrophic water). Out of these 65 species, 18 are known as necrotrophs of fish. The following fungi were recorded for the first time from Poland: Achlya conspicua, Apodachlyella completa, Pythiomorpha undulata, Pythium butleri, Pythium carolinianum, Pythium gracile, Pythium imperfectum, Pythium indicum, Pythium irregulare, Pythium myriotylum, Pythium papillatum, Pythium pyrilobum and Pythium rostratum.
