Psilocybe tampanensis is a rare and rather unimpressive little brown mushroom that was first documented in 1977 by entheo-mycologist Dr. Steven Pollock, and his colleague, writer Gary Lincoff. The specimen was found growing alone in a Tampa Florida sand dune while they were attempting to escape a nearby uninteresting taxonomy conference. Later that day, the fungus’ bruised flesh turned bluish and the gills released purple-brown spores, both signs of a psilocybin-producing Psilocybe.
This moderately to highly psychoactive strain has the particularity to produce a sclerotia, a dormant form of the organism which may also be consumed for its entheogenic properties; the sclerotia is commonly called Philosopher’s Stones or Truffles.
P. tampanensis was reported a little later that year, in Mississipi by Mexican mycologist Guzmán; as it is often said by experts of the field, mushrooms appear where mycologists go.
Nonetheless, this happenstance finding was cultivated by Pollock which helped it spread worldwide. Today, probably because it is considered to be one of the easiest species to grow, Psilocybe tampanensis is cultivated worldwide, mostly for its sclerotia.
It is through the cultivation of these unexpected fortunate discoveries that many rare Psilocybe mushrooms survived.
Other strains that produce a sclerotia are P. semilanceata, Conocybe cyanopus, P. mammillata and, P. mexicana.
