  text: Mycorrhizal and saprotrophic macromycetes contribute strongly to the carbon
    and nitrogen cycles of forest ecosystems, often studied by tracing stable isotope
    composition of carbon and nitrogen. The phenomenon of the saprotrophic-mycorrhizal
    divide highlights the difference in the stable isotope composition of fruiting
    bodies of mycorrhizal and saprotrophic fungi. Much less is known about the isotopic
    composition of the mycelium, which plays an important role in the formation of
    the soil organic matter and fuels the fungal trophic channel in soil food webs.
    In this study, we assessed whether the saprotrophic-mycorrhizal divide in the
    natural δ13С and δ15N values can be traced throughout entire fungal organisms.
    This hypothesis was tested using 16 species of ectomycorrhizal and six species
    of saprotrophic basidiomycetous fungi. We showed that not only fruiting bodies,
    but also the mycelium of ectomycorrhizal and saprotrophic fungi differs in the
    δ13C and δ15N values. In both ectomycorrhizal and saprotrophic fungi, the δ13C
    and δ15N values increased from mycelium to hymenophores and correlated positively
    with the total N content in the corresponding tissues. The differences between
    ectomycorrhizal and saprotrophic mycelium can be used to reconstruct the fungal-driven
    belowground carbon and nitrogen allocation, and the contribution of saprotrophic
    and mycorrhizal fungi to soil food webs.
