In the words of The National Forest Foundation: "Taken together, myecelium composes what’s called a “mycorrhizal network,” which connects individual plants together to transfer water, nitrogen, carbon and other minerals. German forester Peter Wohlleben dubbed this symbiotic network affecting about 90 percent of plant life on the planet -- including trees -- the “woodwide web.” It is through the mycelium that trees 'communicate.'

Botanists and mycologists have understood this grand symbiotic relationship between fungi and plants for over a century. But positing the existence of a linguistic communication system founded on 'intelligence' is another subject entirely.
