New to this forum. I have had experience with MM once. My background is chemistry. I have done a lot of literature research on mushrooms that contain psilocybin. Photo I'm trying to upload is screenshot from literature article on Psilocybe mushrooms

Psilocybin is the phosphorylated prodrug of psilocin, which the actual psychoactive agent found in these 'shrooms. When the 'shroom is injured, oxygen induces the formation of colored dimers, predominantly blue as shown.

Thanks for posting this. 
An interesting topic. I remember mycologist and long time Shroomery contributor Alan Rockefeller quoted or uploaded an article or scientific paper explaining how the bluing process is due to an enzyme in the cell structure, if I'm not remembering incorrctly. I'll see if I find the thread where this was posted, but it was a few years back I believe.
Welcome to the Shroomery.

Thank you.
There are a lot of mushroom species & it's very hard to tell which is which, especially when you are looking for one specfically. Some are very toxic & can kill. Europeans have a long history of collecting mushrooms to eat but here in the U.S. not so much.
The advantage of the blueing reaction shown in the photo I posted is that it takes only a minute & needs no equipment other than a pen knife. Lacking a knife, you can just pinch the cap.
There are 2 other criteria for a successful field trip to collect 'shrooms contaning psilocybin:
Season: very warm Location: S TX near the Gulf coast & S FL. South of Houston In cow fields in dung piles. The 'shrooms broadcast spores onto the grass that the cows eat & pass into their stool where the 'shrooms' spores germinate. They likely can be found elsewhere but your chances of finding them are decreased.
The blueing test is interesting from many POVs. But primarily assuring the collector that he has what he wanted.

Psilocybe cubensis
Dscovered by F.S. Earle in Cuba in 1904 (as Stropharia cubensis), this species is the largest and, arguably, the most handsome of all the Psilocybes. Where other Psilocybes are just plain folk, cubensis is gentry.
In 1907 it was collected in Tonkin (now N. Vietnam) by N. Patouillard, and again in 1939 near Huautla de Jimenez, Oaxaca, Mexico, by acclaimed Harvard botanist and explorer Richard Evans Schultes, who described it in the Harvard University Botanical Museum Leaflets, and deposited specimens in the Farlow Herbarium at Harvard. Schultes was aided by Dr. Blas Pablo Reko, a Mexican naturalist who was one of the first to unravel the mystery surrounding the Indians' use of the divine mushrooms.
Unaware of these previous citings, W.A. Murrill described it in 1941 as the Florida novelty, Stropharia cyanescens. It is also one of the most widespread psychoactive species in the subtropics, ranging from the U.S. Gulf Coast, where it fruits virtually year-round on cow pies, to Mexico, Central America, South America, West Indies, Thailand, Cambodia, India and Australia.
I've lived in S FL & this article confirms that cow pastures there are just as fruitful as S TX. As in TX, the winter months are not as productive as the Spring, Summer & Fall months.

It's a good thing to know for sure - but woe to those who have poor color vision or are just unclear on what exactly "blue" is... Fortunately neither is poisonous, but I've seen plenty of "I found this bluing mushroom what is it!!" and the photo attached is a saffron milk cap (which stains green) or a Stropharia caerulea which is indeed blue, but more of a cyan blue..

The photo I posted was from a peer-reviwed technical journal. There are countless shades of the color blue but if you need a reference, have this pic color printed. Check to see if they got it right.

I'm not questioning your photo... just some people's color vision
(not my own either.. I'm a professional photographer, I have a larger color 'vocabulary' than most and the ability to correctly sort all 100 chips in the Farnsworth Munsell 100 Hue Test... yes that is a minor brag)

Thank you.
I did check that referenced post & found it to be both accurate & interesting. I had not considered the blue-colored oxidation products to be biologically active as pest deterrents but evolution has produced untold numbers of interesting things.
