How Mycelium Communicates: The Internet of the Forest

Discover how mycelium—the underground network of fungi—acts as nature’s internet, helping trees and plants exchange nutrients, warnings, and information in the forest ecosystem.

The Hidden Network Beneath Our Feet

When you walk through a forest, it’s easy to admire the trees, the moss, and the wildlife. But the most fascinating part of the forest is hidden underground. Beneath every step lies a vast, living web known as mycelium—the branching root-like network of fungi that connects plants and trees.

Scientists call it the “Wood Wide Web”, because it functions much like the internet: transmitting signals, sharing resources, and maintaining balance within the ecosystem.

At our mushroom farm in Prague, this same mycelial network forms the foundation of our oyster, shiitake, and lion’s mane cultivation. But in the wild, it plays an even grander role in sustaining life on Earth.

What Exactly Is Mycelium?

Mycelium is the vegetative part of fungi—an intricate web of microscopic threads called hyphae. These threads spread through soil, wood, or organic matter, forming connections with plant roots in a relationship known as mycorrhiza.

Through this partnership, mycelium acts as both a nutrient delivery system and a communication network, linking trees and plants into a cooperative community.

How the “Wood Wide Web” Works
  1. Nutrient Sharing
    Trees and plants exchange carbon, nitrogen, and phosphorus through mycelial networks. A healthy tree might “feed” smaller or shaded plants through fungal connections, ensuring collective survival.

  2. Chemical Messaging
    When a plant is attacked by pests or disease, it can release warning chemicals via the mycelium. Nearby plants “receive” the message and activate their own defense systems before the threat arrives.

  3. Selective Connections
    Mycelium doesn’t just connect anything at random—it forms mutually beneficial partnerships, choosing which roots to attach to, depending on environmental conditions and available nutrients.

  4. Carbon Storage
    Mycelium helps forests store carbon underground, playing a major role in climate regulation and soil health.

Why This Matters for Science and Sustainability

Understanding mycelium communication helps us rethink how ecosystems operate. Forests are not just collections of individual trees—they’re cooperative, interconnected systems.

This discovery also inspires new technologies and biomimicry designs, including:

  • Mycelium-based sensors that monitor soil health

  • Bio-network modeling for ecological restoration

  • Sustainable mushroom farming that mirrors natural cycles

At our farm in Prague, we aim to grow mushrooms while learning from this incredible natural intelligence. By studying how fungi connect and share, we can cultivate more sustainably and contribute to a healthier planet.

The Future: Learning From the Fungal Internet

As research continues, scientists believe mycelium may hold the key to:

  • Regenerating degraded soils

  • Improving carbon capture systems

  • Developing bio-inspired communication technologies

In short, the humble mushroom could be teaching us how to build smarter, more resilient networks—both digital and ecological.

Final Thoughts

The next time you walk through a forest, remember that an invisible network hums beneath your feet. The mycelium web is more than a fungal structure—it’s a living internet that keeps the forest alive, communicating, and thriving.

At our Prague mushroom farm, we grow with the same respect for nature’s networks—sustainably, intelligently, and in harmony with the earth. If you want to know more contact us.
