Mycelia are networks of hyphae. Hyphae are thin, branching filaments that make up the body of a fungus. Mycelia are formed by the interweaving of many hyphae and can cover extensive areas of soil or other substrates. Mycelia serve as the main mode of nutrient acquisition and transport for fungi, enabling them to break down and absorb organic matter from their environment. Therefore, hyphae are the building blocks of the mycelia.
