Gymnopilus purpuratus is a species of agaric fungus in the family Hymenogastraceae.[1] It grows in clusters on dead wood, tree stumps and wood chip mulch. It is widely distributed and has been recorded in Argentina, Australia, Chile, New Zealand,[2] the UK and Germany. It has a broadly convex cap covered in small dry reddish-brown scales, a stout yellow stem beneath reddish brown, wine-red to purple vertical fibres, and a thick rusty orange spore print.[citation needed]

The fruitbodies can stain greenish, blue and purple when damaged, and the species is psychoactive. A chemical analysis carried out by Jochen Gartz in 1993 found that this species contains 0.34% psilocybin, 0.29% psilocin and 0.05% baeocystin.[citation needed]

Gymnopilus purpuratus in New Zealand.
Convex dry scaly cap and colourful fibrous stipe

The cap ranges from 1.5 to 6 cm across, is convex to obtuse, and is reddish brown with a dry scaly surface which is sometimes cracked in age. The stem is brown-red and covered by fibers and has blue-green spots where the stem is damaged. The gills are crowded, yellow to orange, and adnexed. The stem is dusted with rusty orange spores and has a cottony scanty partial veil.[citation needed]
