The carbon-14-labeled carbon dioxide that is released by respiration after glucose labeled with carbon-14 is applied to fungal mycelium can be reabsorbed in highly significant amounts by distant mycelium and agar media in the same petri dishes. Atmospheric transfer of carbon-14 must be considered when using labeled organic compounds to study translocation in fungi.
