As mentioned, the story of Panaeolus cyanescens begins in Asia. However, it’s thought that they were introduced to the Hawaiian islands during the 1800s when cattle were imported from the Philippines. Copelandia cyanescens were first identified in 1871 as Agaricus cyanescens by Berkeley and Broome from a specimen in Sri Lanka. A few years later, Copelandia papilionacea were discovered and documented in the Philippines by Italian mycologist Giacomo Bresadola.
Copelandia cyanescens a.k.a. Panaeolus cyanescens (Blue Meanies)
Copelandia cyanescens are most commonly found in Mexico, Brazil, Bolivia, the Philippines, Eastern Australia, India, Bali, Southeast Asia, Hawaii, Louisiana, and Florida, among other warm climates.
Copelandia cyanescens belongs to the family Coprinaceae, and is primarily dung-loving, but it has also been found in grassland where manure was previously deposited.
