A comparative analysis of the cultured micromycetes in oligotrophic peatlands of natural biosphere reservations located in the northern and central parts of Russia
The current study addresses the fungal diversity of the peatlands that vary geographically and geologically, in the central and northern parts of Russia. The central (Smolenskaya area, National Park «Smolenskoye Poozerie») and northern (White Sea Biological Station area) peatlands have a different g...

In both investigated areas, we found an overall poor species diversity with a high fraction of sterile mycelia.
