The contents of ash and seven trace elements were determined in Xerocomus badius, Ixocomus variegatus and Cantharellus cibarius. The collection included 42 samples from 23 localities. Copper content ranged from 23 to 56 mg/kg dry matter, manganese from 16 to 54, zinc from 95 to 192, cobalt from 1.4 to 2.3, iron from 106 to 1460, cadmium from 0.7 to 1.5 and nickel from 3.3 to 5.0. The content of biogenic elements is species-dependent: Cantharellus cibarius showed high manganese and cobalt; Ixocomus variegatus had high iron and low copper; Xerocomus badius had high zinc. No species-dependent relationship was found for cadmium and nickel. Correlations were observed between copper, zinc and manganese levels.
