Comment: This fungi according to the author smells sweet and spicy not farinaceous and taste rather bitter. 9 specimens of this mushroom from two localities in the Czech Repulic were analysed for psilocine/psilocybine content and showed a high concentration of psilocine as compared to a low content of psilocybine. Higher concentrations of indole derivatives were found in fruitbodies obtained from lower elevations. This is the third bluing Psilocybe described in the Czech Republic.
