Panaeolus cyanescens, also known as Blue Meanies, are a soft, tiny mushroom that grows in warm and tropical environments. The mushrooms spawn upon the dung of cow and water buffalo. The spores are black and the fruiting bodies are usually spotted with blue colored flakes as they get older (hence the name Blue Meanies).
Blue Meanies are well known to contain healthy, rich amounts of psilocine, psilocybin, and are much more psychedelic then less rare/easier to grow strains such as the Golden Teacher. The islanders of Bali, in particular, have a long history with the recreational use of the mushrooms for festivals and celebrations…as well as for creative artistic expression (and for inspiration). Blue Meanies are very commonly sold to travelers and tourists in Bali and similar regions for their hallucinogenic activity.
