Psilocybe tasmaniana

Psilocybe tasmaniana is a species of coprophilous agaric fungus in the family Hymenogastraceae. It was described by Gastón Guzmán and Roy Watling in 1978 as a small tawny orange mushroom that grows on dung, with a slight blueing reaction to damage, known only from Tasmania and southeastern Australia. It was likened to Psilocybe subaeruginosa although characteristics, appearance, and the association with dung were not typical for that species. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin. In 1992 an attempt was made to combine the name as a synonym of Psilocybe subaeruginosa. This was unsuccessful but the species was not well known and it gained a reputation as invalid, and with a lack of authentic records the name fell out of use. In recent years it has been applied to a species in Australia and New Zealand which may or may not be the same species Guzmán and Watling described. There are similarities but it is not on dung, and......read more on Wikipedia.
