Geastrum saccatum, commonly known as the sessile earthstar[1] or rounded earthstar,[2] or star of the land,[3] is a species of mushroom belonging to the genus Geastrum. The opening of the outer layer of the fruiting body in the characteristic star shape is thought to be due to a buildup of calcium oxalate crystals immediately prior to dehiscence. G. saccatum is distinguished from other earthstars by the distinct circular ridge or depression surrounding the central pore.
