Strain Origin: Mexico

Cap: 10-30 mm in diameter, orangish brown to yellowish, convex but occasionally with a rudimentary papilla or umbo. Cultivated specimens sometimes exhibit an irregular edge.

Stem: 50-110 mm long, fibrous and tough especially at the base, staining blue when cut.

Spores: 6.5?8 microns in length, rhomboid to subrhomboid in face view, dark purplish brown in deposit.

Comments: This collection is a direct descendant of cultures made by Heim and Cailleux in 1958 and featured in the historically significant ?Les Champignons Hallucinogenes des Mexique? (Heim & Wasson, 1958). Initially described as Psilocybe semperviva, it was considered an interesting but mutated form of P. mexicana (Heim & Wasson, 1958; and Heim and Cailleux 1958). However, unlike P. mexicana this species does not form sclerotia in culture. Later, Heim (1967) curiously described P. semperviva as being a wild mushroom from Huautla de Jimenez.

It has been noted as slow growing and highly resistant to contamination and decay, which explains the descriptive name ?semperviva? which means ever-living. This is especially appropriate considering that this sample was originally collected over 50 years ago and is still going stong. Guzm?n (1978) eventually determined that P. semperviva is actually a nonpapillate variant of P. hoogshagenii and is now known as P. hoogshagenii var. convexa.
