Physarum globuliferum is a species of slime mold characterized by its small to medium-sized sporocarps, typically 0.5-2 mm in diameter, with a globose to subglobose shape and a short, stout stalk. The peridium is usually yellowish-brown to dark brown, and the capillitium consists of a network of tubular elements. In East and Central Texas, Physarum globuliferum has been found growing on decaying wood, leaf litter, and other organic matter in forests, woodlands, and along streams, with a preference for moist, shaded areas. It is often associated with rich soils and abundant vegetation, and its fruiting bodies typically appear in the spring and fall.
