Abstract

The article presents the results of studying the ability of higher fungi accumulate selenium and other chemical elements. It was established that the mushrooms that grow in the Dniester River valley, accumulate in its fruit body from 0.147 to 24.92 mg Se/kg of dry matter. The concentration of selenium in mushrooms depends on the ecological and geochemical conditions of growth, and the highest concentration observed in the accumulative ecosystems, which are located in the depressions. The content of macro- and microelements in wild and cultivated mushrooms (Agaricus bisporus) differs significantly. 

Keywords: higher fungi, chemical elements, selenium, geochemical landscape, ecosystem.
