- Аннотация: The features of the distribution of the stable isotope composition of carbon and nitrogen for saprotrophic and mycorrhizal macromycetes growing on an oligotrophic peatland were characterized for the first time. The molecular identification of the free-growing mycelium of mycorrhizal fungi detected the presence of both ecto- and arbuscular mycorrhizal fungi. Stable isotope composition of fruiting bodies and mycelium of mycorrhizal fungi of peatland differed fractionally. The fruiting bodies of saprotrophic fungi growing on the surface of the moss cover were enriched in 13 С, but not in 15 N, compared to their main substrate, sphagnum. Differences in the isotopic composition of functionally different parts of the fruiting bodies of macromycetes (hymenophores and stipes) were minor. The mycelium of mycorrhizal fungi of the peatland is enriched in 15 N by 1.4 to 9.5 ‰ compared to the tissues of host plants. These values noticeably exceed similar values that were previously shown for forest ecosystems.
