Mycorrhizal Networks

Mycorrhizal networks are intricate, symbiotic underground associations formed between the root systems of forest trees and specialised soil fungi, acting as a critical biological communication and nutrient exchange web across the forest floor. These underground networks are often colloquially referred to as the 'wood wide web.' The fungal hyphae are microscopic thread-like structures.

Sometimes they can be bundled, creating 'cords' which are easily visible in the ground, especially winding their way through deep leaf letter. The cords of some fungi have been followed travelling hundreds of metres through a forest. Such fungi transport nutrients across the forest.
