Optimum concentrations of heavy metals like copper, cadmium, lead, chromium, and zinc in soil are essential in carrying out various cellular activities in minimum concentrations and hence help in sustaining all life forms, although higher concentration of these metals is lethal to most of the life forms.Galerina vittiformis, a macrofungus, was found to accumulate these heavy metals into its fleshy fruiting body in the order Pb(II) > Cd(II) > Cu(II) > Zn(II) > Cr(VI) from 50 mg/kg soil. It possesses various ranges of potential cellular mechanisms that may be involved in detoxification of heavy metals and thus increases its tolerance to heavy metal stress, mainly by producing organic acids and phytochelatins (PCs). These components help in repairing stress damaged proteins and compartmentalisation of metals to vacuoles. The stress tolerance mechanism can be deduced by various analytical tools like SEM-EDX, FTIR, and LC-MS. Production of two kinds of phytochelatins was observed in the organism in response to metal stress.

Ectomycorrhizal fungi are key players in terrestrial ecosystems yet their mating systems and population dynamics remain poorly understood. We investigated the fine-scale relatedness structure and genetic diversity of Boletus edulis , one of the world's most commercially important wild mushrooms. Microsatellite genotyping of fruiting bodies from 14 different sites around Bielefeld in Germany revealed little in the way of population structure over a geographic scale of several kilometres. However, on a more local scale we found evidence for elevated relatedness as well as inbreeding. We also observed a significant negative association between the genetic diversity of fruit and the age of the trees under which they were sampled. Taken together, our results suggest that as genets mature, they compete and potentially create conditions under which further spores struggle to become established. By implication, even though this species is widely picked, propagules remain common enough to create strong competition when new habitats become available.

Lentinus edodes is one of the most popular edible mushrooms in the market. However, it contains heavy metals that are poisonous to humans even at trace concentrations. The concentrations and bioconcentration factors of five heavy metals in cultivated L. edodes in Chengdu were studied, and the potential health risks to local residents associated with the cultivated L. edodes consumption were evaluated. Total concentrations of cadmium (Cd), lead (Pb), chromium (Cr), arsenic (As), and mercury were determined in the fruiting bodies and the substrate from three agricultural areas. Fruiting bodies samples were collected at different growing times (2, 4, 6, and 8 days). The bioconcentration factors of heavy metals from the substrate to the fruiting bodies were estimated, and the potential health risks of local L. edodes were assessed. Because antioxidant enzymes can resist the creation of reactive oxygen species and defend against heavy metals, the activities of three antioxidant enzymes (superoxide dismutase, catalase, and peroxidase) in the fruiting bodies were also determined. A gradual change in heavy metal concentrations occurred across the growing time of the fruiting bodies. Cd transferred from the substrate to the fruiting bodies in larger concentrations than did Pb, Cr, and As. However, Chengdu residents were not exposed to significant health risks associated with consumption of local L. edodes. Nevertheless, more attention should be focused on children because of their higher sensitivity to metal pollutants.

Background. Many companies in Nigeria generate industrial effluents, including heavy metals. These metals can be accumulated by biota such as mushrooms, which are then eaten by the populace. Objectives. The present study investigates the metal content of wild mushrooms in order to educate the local population on the safety of their consumption. Methods. Seven different species of wild mushrooms (Cortinarius melliolens, Chlorophyllum brunneum, Pleurotus florida, Volvariella speciosa, Cantharellus cibarius, Entoloma spp and Coprinus africana) growing in Ibadan, southwest Nigeria were analyzed for their heavy metal (copper (Cu), cadmium (Cd) and lead (Pb)) contents using atomic absorption spectrophotometry. Results. The concentrations of the heavy metals in the mushrooms and substrate varied by site of collection. The highest concentrations of Cu (92.31±8.42 mg/kg), Pb (76.00±9.78 mg/kg) and Cd (92.45±12.34 mg/kg) were obtained in C. africana, P. florida and V. speciosa, respectively. The lowest contents of Cu (56.00±5.02 mg/kg), and Cd (67.92±5.89 mg/kg) were obtained from C. melliolens, while C. cibarius had the lowest concentration of Pb (40.00±3.56 mg/kg). The highest concentrations of Pb (20.40±3.43 mg/kg) and Cd (26.40±4.34 mg/kg) were obtained in the substrate of C. molybdites, while the lowest Pb (12.40±2.12 mg/kg) and Cd (18.00±3.90 mg/kg) occurred in V. speciosa and C. cibarius, respectively. The bioaccumulation factors of the mushroom species studied ranged from 2.84 – 14.60. Conclusions. The present study found that heavy metal accumulation varied by species of mushroom, metal content of the substrate and the bioavailability of the metal in the mushroom. The level of metals in mushrooms in the present study was relatively high. Therefore, cultivation of mushrooms in heavy metal-free soil should be encouraged. Competing Interests.

 The article is devoted to the problem of consequences of anthropogenic environment pollution with heavy metals and their salts. The review presents data on food products that most actively accumulate them. It is shown that edible wild-growing and cultivated mushrooms are classified as such. At the same time, there are no normative documents regulating the maximum permissible values of heavy metals content for wild mushrooms. Herewith, among the wild-growing mushrooms, there are species that are most prone to the heavy metals accumulation. According to the authors, the issue of studying the accumulation of heavy metals by fungi growing near cities with developed industry is relevant. It is required to develop methodological approaches for their detection in wild-growing edible mushrooms and regulatory documents regulating their admission to the retail network.

Serpentine soil contains highly heavy metals, such as manganese, chromium, cobalt, and nickel,which could bean inappropriate growthmediaofmostplants. Someplants thatfound able to grow optimally on South Kalimantan serpentine soil have been known to do association with ectomycorrhizal fungi. This research aimed to obtain and characterize mushrooms assumed as ectomycorrhizal fungi indigenous South Kalimantan serpentine soil. This study used field exploration of fungal fruiting bodies and identified the genus based on morphological characters of fruiting bodies such as shape, size, and ornamentation, which are unique for the genus identification, then compared the characteristics on mushroomexpert.com. The mushrooms were also confirmed of genera assumed as ectomycorrhizal fungi based on mycorrhizas.info. Seven fruiting bodies were obtained and classified as Cantharellus (Ct), Chlorophyllum (Ch1 and Ch2), Lycoperdon (Ly), Ramaria (Rm1 and Rm2), and Thelephora (Tp). The results showed that all of those fruiting bodies belong to Basidiomycetes. There were 4 genera of Cantharellus, Lycoperdon, Ramaria, and Thelephora, assumed as ectomycorrhizal fungi. But Chlorophyllum genus was never reported as ectomycorrhizal fungus

Food safety is a very frequent topic. The article deals with the problems of fortification of the most grown mushroom in Slovakia, and the 3rd most grown mushroom in the world, Pleurotus ostreatus. Due to the high environmental pollution of soils and air, there is a risk of the production of dangerous fruiting bodies with high heavy metals content. It is known that these substances can promote serious health effects on human body, such as bone weakness or kidney damages (cadmium) and negative process of cognitive developing (lead). The experiment was focused on biofortification with selenium to reduce the accumulation of selected heavy metals (lead, cadmium) in oyster mushroom, grown with intensive cultivation under artificial conditions. This work confirms that the application of sodium selenate to the growing substrate with straw as the main component can reduce the accumulation of cadmium (by 22.45%) and lead (by 64.81%). Research by various authors reported the ability of the oyster mushroom to embed selenium from the substrate into the fruiting bodies. Based on the results of the experiments, we propose to fortify the growing substrate for the production of oyster mushroom by selenium. This way we produce a food with a high antioxidant potential.
