The contents of 21 risk and essential elements were determined in fruiting bodies of four macrofungi species with ecological connection to white birch. Leccinum scabrum and Leccinum versipelle were common mycorrhizal edible mushrooms, while Piptoporus betulinus and Inonotus obliquus were parasitic mushrooms with medicinal effects. The samples were taken from two locations in Šumava mountains - near the town of Vimperk and near the small village of Křišťánovice. Simultaneously with fruiting bodies of mycorrhizal mushrooms, underlying substrates were taken for determination of bioconcentration factors.
