Are mushrooms connected underground in an root complex?

Yes, mushrooms are connected underground in a vast network of fungal threads known as mycelium. This network acts as a root complex, extending far beyond the visible mushroom above ground. The mycelium forms symbiotic relationships with the roots of plants, known as mycorrhizae, where the fungus provides water and nutrients to the plants in exchange for carbohydrates and other essential compounds. This connection between mushrooms and plants through the mycelium is crucial for nutrient cycling, soil health, and the overall functioning of ecosystems.
