I have found several sources recently stating that though the concentration of Psilocybin in P. Semilanceata (Liberty Cap) samples is consistently high, (sometimes reaching 1.1%, more often around .95%), the Psilocin content is remarkably low, in many cases being shown as non-existent, and in others showing .01% or less, whereas in P. Cubensis samples Psilocin averaged around .1% and in Psilocybe Cyanescens around .4%! Is there a cause for the drastic disparity in alkaloid composition, notably of psilocin, between various strains of cubensis other than genetic variability? Also, what effect, if any, does this have on the psychological/physiological manifestations of the mushrooms.
P. Semilanceata are also noted for having a high Baeocystin content, which is Psilocin minus a methyl group, something that is in much lower concentrations in P. Cubensis and Cyanescens. Is there perhaps a cause, in the preferred environment or growth patterns of P. Semilanceata that causes the already relatively unstable Psilocin to lost its methyl group more rapidly (what causes this degradation?), explaining both the high Baeocystin and the low Psilocin contents? There seems to be a definite correlative relationship between high Psilocin and low Baeocystin (or vice versa) concentrations. Any theory (or better yet, evidence) on what would cause this?
