mycelium /mʌɪˈsiːlɪəm/

Mycelium is the vegetative part of a fungus or fungus-like bacterial colony, consisting of a mass of branching, thread-like hyphae.

Referred to as the ‘wood wide web’, mycelium serves as an underlying informational hub for entire ecosystems. It allows plants, trees and microbes to communicate over long distances and to exchange nutrients through the vast network of nodes.
