“…Very high concentrations of toxic metallic elements (Hg, Cd), toxic metalloids (As), essential and toxic nonmetal (Se), and other elements (Ag, Au, Cs, Rb, V, Zn) found in mushrooms from “background areas” have led to many studies which are, however, mostly from European countries. These studies were focused especially on:Toxic metallic elements and metalloids (As, Sb) which might represent a risk for mushroom consumers (see below)Possibilities of using mushrooms for environmental monitoring (Wondratschek and Röder 1993)Radioactive contamination before and after the Chernobyl accident (Reisinger 1994; see below)Chemical form of accumulated elements in mushroom fruit bodies (Collin-Hansen et al 2003; Šlejkovec et al 1997, 2000)Influence of environmental pollution on metallic elements accumulation (Kalač et al 1991; Borovička et al 2006, 2010b; Falandysz et al 2012b; Kojta et al 2012)Chemotaxonomical and mycological systematics significance of trace element accumulation (Stijve et al 1998, 2001; Petrini et al 2009)Mushroom cultivation on artificially metallic element-enriched substrates and media (Falandysz et al 1994b; Crane et al 2010)Use of stable and radioactive isotopes for applications in the study of fungi (Rühm et al 1997; Komárek et al 2007; Guillén et al 2009; Hobbie and Agerer 2010; Agerer et al 2012). …”

This article reviews and updates data on macro and trace elements and radionuclides in edible wild-grown and cultivated mushrooms. A huge biodiversity of mushrooms and spread of certain species over different continents makes the study on their multi-element constituents highly challenging. A few edible mushrooms are widely cultivated and efforts are on to employ them (largely Agaricus spp., Pleurotus spp., and Lentinula edodes) in the production of selenium-enriched food (mushrooms) or nutraceuticals (by using mycelia) and less on species used by traditional medicine, e.g., Ganoderma lucidum. There are also attempts to enrich mushrooms with other elements than Se and a good example is enrichment with lithium. Since minerals of nutritional value are common constituents of mushrooms collected from natural habitats, the problem is however their co-occurrence with some hazardous elements including Cd, Pb, Hg, Ag, As, and radionuclides. Discussed is also the problem of erroneous data on mineral compounds determined in mushrooms.Electronic supplementary materialThe online version of this article (doi:10.1007/s00253-012-4552-8) contains supplementary material, which is available to authorized users.

“…The physicochemical properties of metal-contaminated environments tend to inhibit soilforming processes and affect the area's biodiversity by exerting a strong selective pressure on fungi and plants [16][17][18][19]. Specifically, the bulk metal content of soils and its metal releasability are among the most important edaphic factors determining vegetation composition.…”

Summary 1. Introduction. 1.1 Biodiversity in metal-contaminated sites. 1.2 Selecting native fungi and plants for bioremediation. 2. Case study – Multidisciplinary investigations on biodiversity into a sulphide-rich waste-rock dump. Conclusion: The enormous potential of native fungi and plants that are able to colonize metal-contaminated soils need to be studied in-depth in order to preserve the natural genetic resources of metalliferous habitats and to increase our basic knowledge about the natural adaptation mechanisms of hyperaccumulators in order to employ them in phytoremediation purposes

“…Indeed, the largest loss occurred immediately following the addition of mercury to leaf surfaces in both 2012 and 2013 (Figure 2). It is not known from our THg analyses if the Hg was retained within the leaf, on the leaf surface or associated with microfungi (Fischer et al 1995; Stamenkovic and Gustin 2009; Crane et al 2010) although other studies have suggested that Hg is largely retained in stomatal cavities and thus internal to the leaf surface (Demers et al 2013). …”

Mercury (Hg) is a toxic heavy metal pollutant that is globally distributed due to atmospheric deposition to non-point source locations. Leaf surfaces directly sequester atmospheric Hg. Little is known of how phylloplane (leaf surface) fungi are influenced by Hg pollution. Through culture-based methodology, this study analysed fungal phylloplane community identity following a single-dose response to HgCl2 concentrations between 0 and 20 times ambient levels for New Jersey. Time passed following the Hg addition had a strong influence on the fungal phylloplane community, associated with natural successional changes. Mercury, however, did not significantly affect the phylloplane community identity. Notably, the control group was not significantly different than any of the Hg treatments. How the phylloplane functional group responds to Hg pollution has not been previously investigated and more research is needed to fully understand how Hg influences fungal phylloplane ecology.
