2. Rhizomorphic: Often similar to linear
mycelium, rhizomorphic mycelium is often
called"ropey". In fact, rhizomorphic mycelium
is composed of braided, twisted strands, often
of varying diameters. Rhizomorphic mycelium
supports primordia. Its presence is encouraged
by selecting these zones for further transfer. The
disappearance of rhizomorphs is an indication

of loss of vigor. Lion's Mane (Hericium
erinaceus), the King Stropharia (Stropharia
rugoso-annulata), the Button Mushrooms

(Pleurotus species), Shaggy Manes (Coprinus

comatus), and Hen-of-the-Woods (Grifola
frondosa). Looking like tufts of cotton, the
mycelium is nearly aerial in its growth. Cottony

mycelium is commonly called tomentose by
mycologists. When a rhizomorphic mycelium
degenerates with age, tomentose formations
typically take over.

The more-aged mycelium, towards the center
of the culture, becomes strongly pigmented.
