Hurray for science! Thanks to it and people who believe in it, a small tan spore that has been sprouting happily for Bay Area trippers for decades has a name: Psilocybe allenii. Our friends at the Psychedelic Society of San Francisco tipped us off to the fact that PSSF lecturer and mycologist Alan Rockefeller had helped pen a definitional paper that introduced the little guys. Rockefeller will be leading a Society mushroom hunt -- open to all comers -- in Golden Gate Park on Thu/20. He told us hippies have been hunting Psilocybe allenii in the park for ages, previously using its informal namePsilocybe cyanofriscosa, which sounds suspiciously close to "San Francisco" to us.
