Now all mushrooms previously categorised under Copelandia are universally classified in Panaeolus.

[1] The genus Copelandia was created as a subgenus of Panaeolus 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.

Copelandia species are white to gray or tan, usually with long, thin fragile stem and are delicate.

Blue staining on the caps and stems can often be observed where the mushroom has been bruised due to psilocin content.

None of the mushrooms in Copelandia have a partial veil and the gills always have thick walled pseudocystidia, often with crystals at the ends.
