Geastrum quadrifidum [SEP] Description
As in all "Geastrum" fungi, the internal spore-producing gleba is enclosed in the peridium, a protective structure composed of four layers of tissue: an inner endoperidium, and outer exoperidium that may further be divided into an external mycelial, a tough and membranous middle fibrillose layer, and an internal fleshy layer (known as the pseudoparenchyma). The immature, unopened fruit body is roughly spherical to somewhat flattened or irregular in shape. It lies partly or wholly submerged, encrusted with debris. The expanded fruit body is usually taller than it is wide, about high, with mycelial cup included about . The exoperidium (the outer tissue layer of the four-layered peridium) splits in the middle into three to six, but usually four or five rays.
