Cover illustration: The crystal structures of anhydrous psilocybin Forms A and B have been solved using laboratory powder X-ray diffraction data, refined using synchrotron and laboratory data, and optimized by applying density functional techniques. The crystal structures, along with that of the previously determined trihydrate, permit the quantitative analysis of a variety of historical samples of psilocybin.
