Common names: dung bird's nest, dung-loving bird's nest fungus.
Extract from Wikipedia article: Cyathus stercoreus, commonly known as the dung-loving bird's nest, is a species of fungus in the genus Cyathus, family Nidulariaceae. Like other species in the Nidulariaceae, the fruiting bodies of C. stercoreus resemble tiny bird's nests filled with eggs. The fruiting bodies are referred to as splash cups, because they are developed to use the force of falling drops of water to dislodge and disperse their spores. The species has a worldwide distribution, and prefers growing on dung, or soil containing dung; the specific epithet is derived from the Latin word stercorarius, meaning "of dung".
Cyathus stercoreus is a species of bird's nest fungus that grows in dung, typically from herbivores. In East and Central Texas, it can be found on the ground in fields, pastures, and along roadsides, often associated with cow or horse manure. The fungus produces small, cup-shaped fruiting bodies that are 0.5-1.5 cm tall and 0.5-1.2 cm wide, with a grayish-brown to dark brown exterior and a smooth, whitish interior. The interior contains multiple small, egg-like peridioles that contain the spores. It typically fruits in the spring and fall, and can be common in areas with abundant dung.
