What is mycelium?

Mycelium is indeed the vegetative body of a fungus. It consists of a network of filamentous structures called hyphae, which spread throughout the substrate where the fungus is growing. This network is responsible for nutrient absorption, allowing the fungus to obtain energy and grow. Unlike the reproductive structures of fungi, such as mushrooms or spores, which are involved in reproduction and dispersal, mycelium plays a crucial role in the growth and sustainability of the fungal organism. Understanding mycelium is important in various fields, including ecology, as it helps break down organic matter and contributes to nutrient cycling in ecosystems.
