Lysurus mokusin, commonly known as the lantern stinkhorn, the small lizard's claw, or the ribbed lizard claw, is a saprobic species of fungus in the family Phallaceae. The fruit body consists of a reddish, cylindrical fluted stipe that is capped with several "arms". The arms can approach or even close in on each other to form a spire. The gleba—an olive-green slimy spore mass—is carried on the outer surface of the arms. The fruit body has an odor comparable to "fresh dog feces", "rotting flesh", or "sewage" when mature. The fungus is native to Asia, and is also found in Australia, Europe and
