<P> Mycelium is the vegetative part of a fungus or fungus - like bacterial colony , consisting of a mass of branching , thread - like hyphae . The mass of hyphae is sometimes called shiro , especially within the fairy ring fungi . Fungal colonies composed of mycelium are found in and on soil and many other substrates . A typical single spore germinates into a homokaryotic mycelium , which can not reproduce sexually ; when two compatible homokaryotic mycelia join and form a dikaryotic mycelium , that mycelium may form fruiting bodies such as mushrooms . A mycelium may be minute , forming a colony that is too small to see , or it may be extensive : </P>
