WHAT ARE FUNGI?
Fungi can take many forms, from mushrooms to yeasts, molds, and others. The fungi we use are filamentous, which creates branched microscopic filaments (hyphae). These filaments can grow into large macroscopic structures, which are called mycelium. A fungal organism is usually divided into two parts: the mycelium and the fruiting body. If you think of mushrooms, the mushroom itself is the fruiting body, while the mycelium is a sizeable fibrous structure found underground from where the fruiting body grows.
