“…Those elements are common trace contaminants of mushrooms collected from the wild and cultivated, while sometimes at elevated levels [14]. Apart from the cultivated white button mushrooms, the oyster mushroom Pleurotus ostreatus can accumulate heavy metals at elevated amount if grew in polluted substrates [1,13,36]. The allowed content of Cd and Pb in cultivated A. bisporus offered at the European Union markets should not exceed respectively 0.20 mg kg -1 and 0.30 mg kg -1 (2.0 and 3.0 mg kg -1 dm; assuming 90% moisture content) [10].…”

“…For cultivated mushrooms, the grower may influence the content of minerals and contaminants accumulated in flesh by selection of a proper substrate and cultivation method [22,34]. High quality information on the multi-mineral composition and nutritional characteristics of mushrooms is expanding in the recent years thanks to the modern methods of analysis [2,20,[36][37][38]. A great biodiversity of mushrooms and their emergence at sites that differ in soil geochemistry or a degree of pollution makes study on the wild mushrooms perceived as organic food challenging.…”

Background. Mushrooms are a food that is often considered as an important source of minerals and other nutrients for consumers. There is little data on the minerals in mushrooms processed culinary and on the impact of processing. Objective. The research was aimed at understanding the similarities and differences in the mineral composition (Hg, Li, Mg, Al, Co, Ni, Cu, As, Se, Rb, Sr, Ag, Cd, Cs, Sb, Tl, Pb, U, Ba, Cr, Zn, Mn and V) of white button mushrooms (Agaricus bisporus) processed in industrial conditions. Material and methods. Fungal materials came from six producers. The elements were determined by ICP-MS DRC and CV-AAS using validated methods and QA/QC protocol. The interdependencies of 18 elements and 10 batches of mushrooms examined were tested with the help of principal component analysis. Results. Some significant differences were found in the content and composition of minerals in marinated white button mushrooms depending on producer. Conserved white button mushrooms are poorer in major essential elements but also in toxic Hg, As, Ag, Cd, Sb, Tl or Pb which has been reported for unprocessed mushrooms. Conclusions. The relatively higher levels of Ag in some batches seem to be largely explained by the quality of the substrate used for mushrooms cultivation, while of Li, Rb, Cs, Cr, Al, U, V, As and Mn (in part also of Ba and Sr) largely by the quality of the marinade.

“…The ability of mushrooms to uptake and accumulate a number of environmental contaminants is well established, as extensively shown by numerous field studies and experimental data (Kalač & Svoboda, ; Rzymski, Mleczek, Siwulski, Gąsecka, & Niedzielski, ). Nevertheless, this is highly dependent on environmental quality and can vary between species (Kalač, ; Mleczek et al., ).…”

There is no scientific consensus regarding the safety of the Yellow Knight mushroom Tricholoma equestre (L.) P.Kumm. Following reports of cases of intoxication involving effects such as rhabdomyolysis, and supportive observations from in vivo experimental models, T. equestre is considered as a poisonous mushroom in some countries while in others it is still widely collected from the wild and consumed every year. In this paper, we review all the available information on T. equestre including its morphological and molecular characterization, nutritional value, levels of contaminants observed in fruiting bodies, the possibility of mistake with species that are morphologically similar, and the in vivo data on safety and cases of human intoxication. Based on available data, it is suggested that T. equestre cannot be considered as a toxic species and does not appear to exhibit any greater health threat than other mushroom species currently considered as edible. More care should be taken when reporting cases of human poisoning to fully identify T. equestre as the causative agent and to exclude a number of interfering factors. Specific guidelines for reporting future cases of poisoning with T. equestre are outlined in this paper. Any future research involving T. equestre should present the results of molecular phylogenetic analyses.

The aim of this study was to examine the effects of substrate supplementation with germanium (Ge) and selenium (Se), alone or combined, on the growth, element accumulation and ergosterol content in the fruiting bodies of the mushroom species Ganoderma lucidum and Pleurotus ostreatus. Both species were grown in four independent experimental systems with different concentrations of germanium powder (1, 5 and 10 mM), selenite [Se(IV)] and selenate [Se(VI)] (0.1, 0.4 and 0.8 mM of each Se species). Se supplementation caused no observable changes to morphology while the addition of Ge induced changes in size and/or colour, especially for P. ostreatus. A synergistic effect of Ge supplementation on Se accumulation in fruiting bodies of G. lucidum was observed only at the two highest levels of supplementation with both elements. Even though inorganic Se was used to enrich the experimental substrates, organic Se compounds dominated in the fruiting bodies. Increasing levels of Ge in the substrates elevated the content of organic selenium in the fruiting bodies of G. lucidum. No such trend was recorded in P. ostreatus. The maximum mean Ge levels in P. ostreatus and G. lucidum reached up to 70 and 80 mg kg −1 , respectively. However, the bioaccessibility of this element was low, in the range 5.4-6.6% (P. ostreatus) and 0.4-7.6% (G. lucidum). Ergosterol content in the fruiting bodies of both species displayed the highest values in all the experimental systems supplemented with Se. The addition of Ge and Se + Ge resulted in losses of ergosterol content in comparison to cultivation with Se supplementation and control. The obtained results show the significant role of Ge-Se interaction in the accumulation of these elements in the studied mushroom species.
