(Agaricaceae - Blaetterpilze)
Strophariaceae - Schuppenpilze/Traeuschlingsartige
Habit, habitat, and distribution: Solitary to gregarious, infrequently cespitose, in soils rich in woody debris, in humus, and sometimes on clay soils. Found along trails, shady banks, and in coffee plantations. Discovered by Dr. Thiers in Florida Highlands Hammock State Park). Also reported from Jamaica, Mexico, and Bolivia. (www.shroomery.org)
Guzman et at. (1993) reports that this species is active, although no analyses are cited. The classic bluing reaction leaves little doubt about its activity, although estimation of potency would be purely speculative. This mushroom is probably widely distributed throughout much of Florida but goes unrecognized by most hunters of the more massive psilocybe cubensis. (www.shroomery.org)
Diese Pilzart gehoert zur Gattung Psilocybe (den Kahlkoepfen). Diese Gattung ist bekannt durch eine Reihe halluzinogener Vertreter. So ist Psilocybe semilanceata (der Spitzkegelige Kahlkopf), der psychotrope Pilz Europas. Die Art Psilocybe cubensis ist dadurch beruehmt geworden, dass er sich leicht zuechten laesst und hat damit eine weite Verbreitung in der Drogensubkultur erhalten, wo er als Quelle fuer das begehrte Psilocybin dient. Die Gattung der Kahlkoepfe ist die noch am besten untersuchte halluzinogene Pilzgattung. Die beste zusammenfassende Arbeit stammt uebrigens von dem liechtensteiner Drogenforscher G. Guzman und wurde unter dem Titel "The Genus Psilocybe" veroeffentlicht, ist aber leider schon vergriffen. Dennoch sind noch alle Arten auf ihren moeglichen Gehalt an halluzinogenen Tryptaminen untersucht worden und es gibt noch eine Reihe von Problemen, was die Abgrenzung einiger seltener Arten voneinander betrifft.
