KROUPA M., KALAČ P., DRBAL K. (1980): The variability of the contents of trace elements in some edible mushrooms. Česká Mykologie 34(1): 9-12 (published: 1980)
abstract
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.
DRBAL K., KALAČ P. (1976): Content of cobalt in some edible mushrooms. Česká Mykologie 30(1): 24-26 (published: 1976)
abstract
In this paper the content of the trace element cobalt was determined in 15 species of common edible mushrooms from three localities of the South Bohemia region. The content varied in the range from 0.3 to 4 mg Co/kg of dry matter. The highest content of cobalt was found in Xerocomus subtomentosus (L. ex Fr.) Quél., Agaricus campestris L. ex Fr. and Ixocomus variegatus (Sow. ex Fr.) Quél., the lowest one in Xerocomus badius (Fr.) Kühn. ex Gilb. The determined content in the same species of mushroom found on different localities differed, what proved the influence of every particular place where a mushroom was found. The possible factors are discussed.

abstract
Copper content was measured in 15 edible mushroom species from South Bohemia. Concentrations ranged from 8 to 179 mg/kg dry weight, with Lepiota procera showing the highest levels. Results varied by location, with implications for human dietary intake of copper.

abstract
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.
