Gymnopilus Species Guide

Gymnopilus is a genus of gilled mushrooms within the fungal family Strophariaceae containing about 200 rusty-orange spored mushroom species. Approximately fourteen members of Gymnopilus contain psilocybin although their bitter taste often deters recreational users. 

The fruit body is typically reddish brown to rusty orange to yellow, medium to large, often with a well-developed veil. Most members of Gymnopilus grow on wood but at times may appear terrestrial if the wood is buried or decomposed.

Do not use this information to pick mushrooms in the wild, Gymnopilus is often confused with Galerina, which contains deadly poisonous species.

It should be noted that although these different strains do possess different concentrations of psilocybin and psilocin, factors such as dosage, set, and setting are arguably more determinant of the outcome of effects experienced.   Read Frshminds’ article “Understanding and Measuring Magic Mushroom Potency” to learn more.
