Gymnopilus Junonius

Gymnopilus junonius, commonly referred to as the Laughing Gym or Spectacular Rustgill, is a large, vibrant mushroom known for its striking orange to rust-colored cap and unique properties. This species is widely distributed across North America, Europe, Asia, and Australia, typically found growing on decaying wood, particularly logs, stumps, and buried roots of hardwoods and conifers.
Gymnopilus junonius is a saprotrophic fungus, breaking down lignin in wood and contributing to the nutrient cycling of forest ecosystems. It typically fruits in late summer through autumn and thrives in damp, shaded environments.
This mushroom contains psychoactive compounds, including psilocybin, though in variable concentrations. Its effects and potency make it a subject of interest in the study of psychoactive fungi, but it is less commonly sought after for recreational use due to its bitter taste.
