What to do if you are looking for the “ultimate guide for safe mushroom picking”? Frank and Cheeri Rinaldo had the answer in 1979 with Safe-pik, a flip book of handy mushroom identification cards featuring photographs by John W. Allen. Measuring only about 2 1/2 by 4 inches it could easily fit in your pocket and deals mainly with Psilocybins, the type of mushrooms that contain a naturally occurring psychedelic compound. There is a helpful disclaimer that children should not take mushrooms, one should never trespass, and that mushrooms should be used for the purpose they were intended … mind expansion.
Visual identification of mushrooms is hardly a new concept, as seen by the German publication Naturgeschichte des Pflanzenreiches in Bildern by Dr. Gotthilf Heinrich von Schubert.
