Mycorrhizal fungi transfer nutrients to plants in exchange for photosynthates. Plants allocate up to 20% of their carbon to mycorrhizal structures, mycelium and fruit bodies of their fungal partners. Individuals of mycorrhizal fungi may encompass hundreds of square metres of soil and defragmented litter, linking multiple plant individuals of different species and size (Figure 1). Using a free‐air 13 CO 2 enrichment (web‐FACE) technique in a mature forest, interspecific transfer accounted for 40% of fine root carbon after 5 years of back and forth transfer between trees. In this issue of Molecular Ecology, Rog, Rosenstock, Körner, and Klein (2020) show that closely related trees shared relatively more mycorrhizal fungi than distantly related trees in the same experimental site, which correlated to increased carbon sharing.
