Gymnopilus purpuratus, also known as the purple-gilled gymnopilus or Gypsy mushroom, is a species of mushroom that can be found in Asia and Europe. It belongs to the family Hymenogastraceae and was first described by renowned mycologist Elias Magnus Fries in 1818. Its distinctive purple gills give it its common name, and it is known for its vibrant colors and striking appearance.
Gymnopilus purpuratus grows in clusters on decaying wood, particularly beech and oak trees. The cap of the mushroom can reach up to 8cm in diameter and is convex with a slightly depressed center. Its color ranges from orange-brown to reddish-brown, with a smooth and dry surface. The gills are initially pale yellow but turn purple as the mushroom ages, making it easily identifiable in the wild.
One of the most unique features of Gymnopilus purpuratus is its ability to bioluminesce. This means that under certain conditions, the mushroom can emit a faint greenish light, adding to its mysterious and magical appearance. The cause of this bioluminescence is still unknown, but it is believed to serve as a defense mechanism against predators.
In traditional medicine, Gymnopilus purpuratus has been used for its supposed medicinal properties. It was believed to have anti-inflammatory and pain-relieving effects, and was also used as an aphrodisiac. However, there is no scientific evidence to support these claims and consuming the mushroom can be dangerous as it contains toxic compounds.
Despite its alluring appearance, Gymnopilus purpuratus should not be consumed without proper identification by an expert. Some species of Gymnopilus are known to contain psychoactive substances such as psilocybin and psilocin, making them hallucinogenic. Ingesting the wrong species can lead to serious health consequences, so it is important to exercise caution when foraging for mushrooms.
