Copelandia is a now
deprecated genus of
mushrooms consisting of at least 12 species. Many American
mycologists previously placed members of
Panaeolus which stain blue into
Copelandia, whilst European mycologists generally used the name
Panaeolus instead. Now all mushrooms previously categorised under the Copelandia genus are given the name Panaeolus universally. The
Copelandia genus was 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.
