An accidental case of mushroom poisoning led to the detection of psilocybin in G. validipes (Cortinariaceae). This compound was subsequently isolated (0.12% yield) by anion exchange and cellulose chromatography. Eighteen additional species of Gymnopilus were screened by a method capable of detecting 0.0004% psilocybin in dried carpophores. Psilocybin was detected in G. aeruginosus, G. luteus, G. viridans and G. spectabilis. The latter species has been previously reported to be hallucinogenic. This is the first report of psilocybin from this genus.
