Summary:
A new method to calculate the transfer of nitrogen from Arctic mushrooms to plants is shedding light on how fungi living symbiotically on plant roots and transfer vital nutrients to their hosts.

Cortinarius favrei grows in the midst of dwarf Betula and Salix, Vaccinium, and Eriophorum in the Alaskan tundra. At the Arctic LTER site, isotopic measurements indicate that mycorrhizal fungi function similar to this species contribute 60-90% of their plant's nitrogen while using 8-16% of their net photosynthesis.
