Fungi mycelium network

Mycelium networks are the underground root-like structures of fungi, connecting plants and enabling nutrient exchange across ecosystems.

About this subject

Mycelium is the vegetative part of fungi, composed of hyphae that form extensive underground networks. The largest known organism is a mycelium of Armillaria ostoyae in Oregon, covering 9.6 km² and estimated to be thousands of years old.

Ecologically, mycorrhizal fungi associate with plant roots, exchanging nutrients like phosphorus and nitrogen for carbon. This symbiosis is essential for 90% of terrestrial plants. Mycelium can also transmit chemical signals, often referred to as the "Wood Wide Web."

Human uses include bioremediation (mycoremediation) to break down pollutants, production of mycelium bricks, sustainable packaging, and edible mushroom cultivation. In construction, mycelium is used as insulation and as a plastic substitute.

Scientifically, studying mycelium networks helps understand soil health, carbon sequestration, and sustainable agriculture. Recent research maps electrical signals in mycelium to decode fungal communication.

Frequently Asked Questions

What is the mycelium network?

It's the underground network of fungal threads (hyphae) that connects plants and facilitates nutrient exchange.

How does mycelium benefit plants?

Mycorrhizal fungi extend plant root systems, increasing water and nutrient absorption, especially phosphorus, in exchange for sugars.

Can mycelium be used in technology?

Yes, mycelium is used in biodegradable packaging, construction materials, and even as a potential computer substrate due to its electrical signaling.
