Boletus manicus is a species of fungus in the family Boletaceae of mushrooms. Found in the Wahgi valley Papua New Guinea, it was first described by French mycologist Roger Heim in 1963.[1] Heim singled out this mushroom largely because of its similar appearance to Rubroboletus satanas.[2] Reported to be psychoactive, the active principles are thought to be three indolic substances, but their concentration in the mushroom is too low to allow for chemical analysis and identification.[3]
In the Wahgi language it is called gegwantsyi ngimbl. The word ngimbl in the south Wahgi dialect means pain, which describes the intense bitterness of the mushroom.
