The fruit body, initially shaped like a puffball, is encased within an outer covering that splits open from the top to form rays. These rays curve down to expose an inner papery spore case, which contains the fertile spore-bearing tissue, the gleba. The fungus is unique among the earthstars in having a spore case that is supported by multiple stalks, and is perforated by several small holes suggestive of its common names salt-shaker earthstar and pepperpot. It is the largest of the earthstar fungi, and reaches diameters of up to 12 cm (4.7 in). Its spherical spores have elongated warts that create a ridge-like pattern on their surface. The spores are dispersed when falling water hits the outer wall of the spore sac, creating puffs of air that force the spores through the holes.
