A cluster of oyster mushrooms adheres to rough bark, their fan-shaped caps fanning out in layered, overlapping shelves. Each cap boasts a smooth, slightly velvety surface, ranging in color from milky white to soft grey or pale tan, sometimes with a subtle pearlescent sheen. Distinct, delicate gills radiate across their pale undersides. The mushrooms appear pliable yet firm, their soft forms contrasting with the rugged, textured surface of the dark, craggy bark from which they emerge.
