Mycelium
Mycelium (my·ce·li·um)
Mycelium (/maɪˈsiːliəm/), from the Greek mykēs (fungus) and hēlion (little sun), is the vegetative part of a fungus or fungus-like bacterial colony, consisting of a mass of branching, thread-like hyphae.
Definition
Mycelium is the part of the fungus that absorbs nutrients from the environment. It is through the mycelium that a fungus absorbs nutrients from its environment. It does this by excreting enzymes into the surrounding environment that break down organic matter into simpler compounds that the fungus can absorb and use to grow.
Structure
Mycelium is made up of hyphae, which are long, thread-like structures that penetrate the fungus's food source. The hyphae are typically only one cell thick and are therefore nearly invisible to the naked eye. However, when many hyphae group together, they form a visible mass known as mycelium.
Function
The primary role of mycelium is to provide the fungus with nutrients and water. It does this by extending into the environment and breaking down organic matter into simpler compounds that the fungus can absorb. In addition to providing nutrients, mycelium also plays a crucial role in the reproduction of the fungus. It does this by producing spores, which can then be dispersed to new locations where they can germinate and form a new fungus.
