Gymnopilus aeruginosus is a psilocybin containing species that thrives on decaying hardwoods and wood chip beds. This psychoactive species produces rust orange spores, so thick they will turn your fingers orange when handling the spore. Gymnopilus aeruginosus can be found in the fall, spring and winter seasons, with heavy populations found in the Pacific Northwest of the United States. These spore prints were collected in western Oregon near the coast. They come on small coin dishes, and are packed with tens of thousands of spores.
