Fungi play a key role in the functioning of soil in terrestrial ecosystems, and in particular in the remediation of degraded soils. The contribution of fungi to carbon and nutrient cycles, along with their capability to mobilise soil trace elements, is well-known. However, the importance of life history strategy for these functions has not yet been thoroughly studied. This study explored the soil-fungi relationship of two wild edible fungi, the ectomycorrhizal Laccaria laccata and the saprotroph Volvopluteus gloiocephalus. Fruiting bodies and surrounding soils in a mine-spill contaminated area were analysed. Isotope analyses revealed Laccaria laccata fruiting bodies were ¹⁵N-enriched when compared to Volvopluteus gloiocephalus, likely due to the transfer of ¹⁵N-depleted compounds to their host plant. Moreover, Laccaria laccata fruiting bodies δ¹³C values were closer to host plant values than surrounding soil, while …
