What is mycelium?

Written by: Eva Zonneveld

Mycelium is the underground fungal structure connecting plants, trees, and soil life in a living, breathing ecosystem. Often described as the "internet of nature," due to its ability to exchange nutrients and information between plants. In this blog, we delve deeper into the mysterious world of mycelium and explore how it plays a crucial role in ecology.

Structure of mycelium

Mycelium consists of a network of hyphae, long, thin, branched structures moving through soil, wood, and other substrates. These hyphae can extend over large distances, forming extensive underground networks, serving as the fungus's nutrient uptake system, absorbing water and minerals and transporting them to the fungus's fruiting bodies, like mushrooms.

Ecological importance

Mycelium plays a pivotal role in Earth's ecosystems. Here are a few ways it does this:

  • Food web: Mycelium is part of the food web, acting as both a producer and a decomposer, contributing to soil fertility by breaking down organic material.
  • Soil structure: It aids in stabilizing soil structure, increasing water retention, and enhancing soil fertility, crucial for plant growth.
  • Plant health: Mycelium forms symbiotic relationships with plants through mycorrhiza, where plants provide carbohydrates in exchange for water and nutrients absorbed by the mycelium.

Sustainable applications

Mycelium is increasingly recognized for its potential in sustainable applications:

  • Biological control: Some types of mycelium can be used as biological pesticides against pests and diseases, reducing the need for chemical pesticides.
  • Biodegradable materials: Mycelium is used to create biodegradable materials like packaging and building materials, serving as an environmentally friendly alternative to plastics.
  • Food and medicine: Certain mushrooms, the fruiting bodies of mycelium, have long been used as a food source and for medicinal purposes due to their nutritional value and therapeutic properties.

Future perspectives

Through research and development, we can better understand how to leverage mycelium for ecological restoration, sustainable agriculture, and the development of innovative, environmentally friendly materials.


Mycelium is a marvel of nature, a hidden network supporting and connecting life on our planet. By studying and utilizing this underground "internet of nature," we can not only restore and preserve the health of our ecosystems but also develop new, sustainable solutions that help us form a more harmonious relationship with the natural world. The importance of mycelium in ecological processes and its promising applications make it a fascinating and vital part of our world.
