The genus Copelania is a genus of mushrooms consisting of at least 12 species. Most have a long, thin fragile stem and are delicate, growing in grasslands on dead moss, dead grass, sand dunes, decayed wood, and dung. They are found in the tropics and neotropics of both hemispheres. The Copelandia genus is a subgenus of Panaeolus created by Abbé Giacomo Bresadola (1847-1929) in honor of Edwin Bingham Copeland (1873-1964), an American who gathered fungi in the Philippines and sent some collections to Bresadola. Many American mycologists place members of Panaeolus which stain blue into Copelandia, but many European mycologists use the genus Panaeolus instead. At the moment the species names of both genuses are synonyms.
