Ash, iron and manganese contents were determined in 15 edible mushroom species from three localities in South Bohemia. Ash content ranged from 5–15% of dry matter, iron 70–1530 mg/kg, and manganese 9–100 mg/kg. The highest concentrations were found in Ixocomus variegatus, the lowest in Xerocomus badius. Results varied by site, showing habitat influence.
