Pileus (Cap): 20-50 mm Broad, reddish-brown, with small erect scales appeareaing dense, especially in age, not viscid, convex, obtuse or subumbonate with a slight umbilicus in the center.
Lamellae (Gills): Slightly crenulate, close, rounded-adnexed. Yellow (nankeen to primrose).
Stipe (Stem): 25-55 x 3-9 mm. Brazil brown (brown-red) covered by fibrils. Equal and dusted by spores in age. Context purple, often disappearing, fleshy, developing in most specimens blue spots or areas along the surface where the stems have been touched or scratched. Veil thick and black
Microscopic features: Spores rusty brown-orange in deposit, 8-9 (11) X 4.8-5.5-(6) um. verrucose in circumference, without plage and without a germ pore.
Season: June through November.
Habitat and Distribution: On dead hardwoods and probably conifers, The Austral Floral Zone, Chili, Argentina, Great Britain and Germany.
Growth Habit: Gymnopilus purpuratus is found growing solitary to gregariously or in small clusters
Bruising: Green or blue bruising at the base and on the pileus, green spots on the pileus likely.
Other Notes: This species was first identified in Australia by mycologist John Burton Cleland as Flammula Purpurata (derived from the Latin Purpuratus, clad in purple). Cleland described this species as being found on fallen trunks of wood. Gymnopilus purpuratus is an agaric identified from the austral floral zone and was also collected in Chile and identified by Singer in 1951, who also identified this species from Kew gardens in Surrey. This species blues easily, taste very bitter and is probably hallucinogenic. 1992 chemical analysis of collections from Germany by Dr. Jochen Gartz of the University of Leipzig and others have demonstrated high levels of psilocin and low levels of baeocystin. Dr. Gartz reported that "since 1983, this species has been observed on heaps of pig dung and woodchips in the district Rostock, Northern G. D. R. (East Germany). A chemical analysis done by Jochen Gartz found that this species contains 0.34% psilocybin, 0.29% psilocin and 0.05% baeocystin.
