Mycelium

The body of a fungus that reaches out beyond a plant's roots and into the soil - a fan of countless microscopic threads. The mycelium is the living cable of a mycorrhizal network: because the filaments are only a few thousandths of a millimetre across, the mycelium folds an enormous surface area into a tiny volume, multiplying a plant's nutrient-gathering reach several hundredfold. A single gram of healthy forest soil can hold up to ninety metres of it.
