“…Reczyński and others () found Cd mean value of 1.02 ± 0.04 mg/kg DW in B. badius ( n = 6). Higher Cd contents in 7 wild Boletaceae species were reported by Venturella and others (), that is in the range of 1.20 to 14.80 mg/kg DW. Similar Cd content of 2.77 mg/kg DW in B. edilus was given by Liu and others ().…”

Eight wild edible Boletaceae mushrooms (227 samples) and their soils were collected from 40 locations, Yunnan province, China. Four essential metals (Fe, Mg, Zn, and Cu) and 2 toxic metals (Pb and Cd) were determined. The results showed that Boletaceae mushrooms have abundance of 4 essential metals. The highest Pb mean value was 0.70 mg/kg DW, lower than legal limits, but Cd contents significantly exceeded legal limits. Generally, bioconcentration factor (BCF) indicated that Zn and Cu were easily bioaccumulated by mushrooms. However, the BCF of Boletus griseus reached to 6.40. Target hazard quotients showed Cd was the main risk metal in Boletaceae mushrooms. The metal compositional variability and the similarity of metal contents were further determined by principal component analysis. Regression model analysis indicated that Cd contents in mushrooms were positively correlated with soil Cd contents, and negatively correlated with soil pH, except for the samples of Boletus bicolor.

“…However, such information should be evaluated with care since it is known that the nature of the cultivation substrate could considerably affect the mushroom content [21,22]. Similarly, metal accumulation in wild edible mushrooms was found to be influenced by various factors, including the species, the available concentration of elements in soil substrates, the substrates' properties (e.g., pH, organic matter content), the antagonistic and/or synergistic effects among elements, and the concentration of other elements in mushrooms [23][24][25][26].…”

Albino Grifola frondosa (Dicks.) Gray “maitake” mushrooms (described as G. albicans Imazeki and then placed in synonymy with G. frondosa) are particularly rare, and the few pertinent records are not treated in scientific publications. A field investigation carried out in Sicily (Italy) led to the collection of an unusual white Grifola specimen at the base of a living tree of Quercus pubescens Willd. s.l. The outcome of sequencing the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) indicated that it belongs to G. frondosa and provided an insight to the phylogenetic relationships within the genus. The results of nutritional composition analysis showed that the albino basidioma possesses relatively high contents of Ca, Fe, K, and Cu and is rather low in Na when compared with literature data on edible mushrooms. Vitamin (B1, B2, B3, B5, B9, and D2) contents ranged from 0.15 to 3.89 mg per 100 g of mushroom dry weight. The cold-water extract of this specimen was effective at inhibiting the growth of Staphylococcus epidermidis ATCC 12228 and Pseudomonas aeruginosa ATCC 15442 at the maximum screening concentration of 50% v/v. In addition, the extract slowed down the ability of Staphylococcus aureus ATCC 43300 to form biofilms. According to data hereby reported, the albino G. frondosa is a culinary-medicinal mushroom with a promising exploitation potential.

“…We were also interested in understanding whether different species of edible wild mushrooms collected from similar geological sites would exhibit differences in the accumulation of elements. We compared our dataset with that of Venturella et al [ [4,6], the bioconcentration of the other elements appeared to be element-and species-depended. For example, Co, Cr, Fe, Mg, Mo, Pb, U, and V was four folds higher in C. prunulus than that detected in the bolets analyzed from similar geological sites.…”

“…It is well known that fungi accumulate chemical elements from their environment, particularly from soils and soil solutions [1][2][3][4][5][6]. The mineralogical composition of soil influences the availability of chemical elements and the mycelia of fungi absorb and accumulate all kinds of elements from their growth substrates.…”

“…In several studies, the presence of heavy metals in edible and nonedible fungal species from both, polluted and unpolluted sites, has been analyzed [1][2][3]5,9,17]. However, till date, very few studies have actually analyzed the influence of geology, soil-mineralogy, and soil-chemistry on the chemical content of the fruiting bodies or investigated the correlation between chemical elements in fungi and their soil of growth [4,8,11,18]. For instance, Nikkarinen and Mertanen [8] analyzed the content of elements in two ectomycorrhizal species namely Boletus edulis Bull.…”

Chemical elements in the samples of wild edible mushrooms of the Morchella group collected from different unpolluted Sicilian sites was analyzed by the ICP-MS (method) to detect the content of their minerals and determine whether soil geology and geochemistry can influence the chemical composition in fungi. Results showed that the mushroom samples mainly contained a high concentration of K and P and a wide variety of minor and trace elements (V, Mo, Pb, Ce, Cs, Zr), including heavy metals. Statistical analysis showed that the mushrooms differed in their content of minor and trace elements based on the geological/geographic site of origin. Comparison with other studies showed differences in the content detected in the Sicilian morels with those collected from other geographical sites. Conversely, different fungal species collected from similar geological sites in Sicily showed different patterns of accumulation of the elements confirming that bioconcentration in fungi is species-and site-dependent.
