Violet fungi resemble shriekers and are often found growing among them. Cormanthor violet fungi are smaller than the "normal" variety and are found near treants. Unlike normal violet fungi, which are 4-7 feet tall and almost exclusively subterranean, Cormanthor violet fungi rarely exceed 3 feet in height and grow on the forest floor. Tiny tendrils extend from the base of the fungi, tap into the treant's roots, and worm upward into the treant's trunk. The fungus lives on the treant's sap.

Should a predator threaten the treant, the fungus flails with its branches, attempting to rot the predator's flesh. A treant may be surrounded by as many as six violet fungi, but two or three are typical. When the treant moves, its fungi move with it.
