Naming
First described as "Agaricus coprophilus" by Jean Baptiste François Pierre Bulliard in 1793, it was transferred to the genus "Psilocybe" by Paul Kummer in 1871. In the first decade of the 2000s, several molecular studies showed that the "Psilocybe" was polyphyletic, and the non-bluing species were transferred to "Deconica".References:
