Stone ear is also known as stone fungus, rock mushroom, umbilical cord clothing, stone wall flower. It is named because it resembles an ear and grows in the shady rock crevices of cliffs. The body is flat, irregularly rounded, brown on top and black tomentose on the back.

The lichen body is unilamellar, square and round when young, ellipsoid or slightly irregular when grown up, 12cm in diameter and up and down, and up to 18cm in size, leathery. Lobes edge shallow tear-like, upper surface brown, nearly smooth, local rough lusterless, or local spots off and exposed white medulla, the lower surface brownish black to black, with fine granular protuberances, densely black thick and short and forked pseudopodia, the central umbilicus greenish gray to black, 5-12mm in diameter, and sometimes from the umbilicus to the surrounding radiation of the veins obvious and prominent.
