  | Green and Blue Staining brown capped cyenscens
As we all know, many species of Psilocybe are hygrophanous. that is they change color when drying and with age. First we have the blue oxidation of psilocine which occurs when the flesh of the mushroom is damage and exposed to oxygen. The Caps of many Psilocybes have tones and hues if colors ranging from an olive-brown to a caramel when fresh. As they dry, whether from natural elements as from the heat of the sun or with age, they began to become a straw-yellow color. This straw yellow color mixes with the blue oxidation of the shroom produing the escaping psilocine feromthe mushroom and that occcues when the damaged or aged portions of the mushrooms are exposed to air. As this color change occurs, the Blue colors form from a sly blue azure to a dark indigo and began to appear, sometimes as a very deep blue and the intense bluing results often occuring in the stipe of the mushroom or along the outer edges of the caps of certain species which contain psilocine/psilocybine. Sometimes the bluing reaction is of an azure hue and the blue and yellow mix to produce a deep sea green color. I am only presenting ten images of some of the unusual tones of this blue and green oxidation. I want to point out that the actual; color of some of the caps in these last 7 wood chipped cyans were not of the normal caramel color of cyan caps but instead were of a coffee and/or chocolate brown color rather than the normal caramel color of the caps cyanescens are noted to have in their physical description (Hm! That was a littkle redundant). Here are two images of Psilocybe cyanescens from wood chips which stained green in the caps in the first image and in the second image also stained a deep sea green along and around the outer edges of the caps of those larger specimens .   Here we have am intense blue staining reaction to two large specimens of P. cyanescens which occurred from a grassy laen area where grass was seeded over a mulched bed of alder, The grass in this location grew to a height of at least four to six inched high throughout the lawn and a cold rain and heavy breezes overnight caused the bluing reaction damage to the cpa and stems from an intense blowing of the wind. These two sized shroom would be approzimately 3-3 good doses of psychoactvity.  Now these last 7 mushrooms had an almost chocolate brown color to the cap and the usual white stems. This bluing occured due to am over night extreme wave of cold air which in turn caused a light freeze and the following day had warmed up somewhat which caused the bluing reaction to mix with the brown color hues of the caps. You will notice one large cap in one of the images does display tones of the normal caramel color usually associated with P. cyanescens and indeed it was the cold which caused the oxidation to these paticular shrooms/        mjshroomer by the way, the dark blue lawn shrooms were also very healthy and in good condition for human consumption,despite their raggety look. Although they oxidised and became a dark indigo blue, they were not rotted in any way so they were good enough to digest without any fear of unpleasant stomach reactions, |

Nice pics! I knew I should have taken a pic of one azure, from my outside bed, that was black, stem to cap! The thing that was cool ab out it was it continued to grow with the rest of the flush.

No, They do not and while certain species have bluing, not all mushrooms in a particular species will blue when handled. And not all of the time. And many already have bluing from natual elemental damge as noted here. Some species can have intense bluing and some may not have any at all. The object when picking is too not cause any bluing oxisation as it is the psilocine excaping into the air. First we will observe some bluing naturally in Copelandia cyanescens.        And then I show a tray of Copes where I have picked them with the utmost care and tenderness so as to not squeeze them so that they bruise blue.  See below for more species which have bluing in them. mjshroomer Last edited by mjshroomer; 10-29-08 at 14:11. Reason: typos | |
