agrocybe with bluing ID

Previously had a few growing in same general area IDed as agrocybe sp., but was wondering if these might be different. Are any species of agrocybes known to be edible/active? I noticed that a few of the small ones exhibit a dark bluish color on the cap that seems to dissipate with aging/drying. I am going to try to keep these moist and watered to see if a few mature specimens maintain the shade.
Habitat: mulch, eastern US
Gills:brown to tan
Stem:
Cap: brown with dark possibly blue margin
Spore print color: pending, but others were purple brown if I remember correctly
Bruising: note the darkness on cap..I'm color blind so can't tell hue
Other information:
   
Below - little one's look dark on cap?

No, it's more likely something similar to A. sororia. It's not bluing.

I'm not seeing anything that looks like bluing. Got pics of the gills and/or spore print? Looks like an Agrocybe. If so, the spore print shouldn't be purple-brown. Sounds like confirmation bias.

ahh..thanks, they do look almost exactly like the sororias on mushroomexpert..I will try to get a spore print. I think it probably was/is confirmation bias.

Thanks! will do.. I was thinking though, after the comment about A. Sororia, I did some searches and found that A. Farinacea is actually a variety of A. Sororia (link:http://www.mycobank.org/MycoTaxo.aspx?Link=T&Rec=347734)
In addition, since the genus Agrocybe has not had much analysis done to identify macro or microscopic features of all the species yet, it is conceivable that bioassaying would be the fastest method of determining if this is a Farinacea variety. If that is possible, is there any chance it is a poisonous species..spore print is pending..what should I look out for?

A farinacea is not a variety of A. sororia. The mycobank record is for Agrocybe sororia var. farinacea, a variety of A. sororia.
All Agrocybes smell farinaceous. (like cucumber)
All Psilocybes and all other psilocybin mushrooms also smell farinaceous.
Workman thinks that the test result which shows that A. farinacea has psilocybin is a false positive, and I think he is very likely to be correct. I have not seen any pictures of A. farinacea with blue staining, nor any trip reports.

I have heard that there are poisonous members of Agrocybe but I haven't seen any proof and I think its likely that they are all edible.
I found a blue/greenish Agrocybe in Mexico last year, unfortunately it rotted before it dried. I will check the spot again in a few months.

Ahh..ok thanks a lot!

I was just about to start a thread requesting anyone who knows which Agrocybe species are poisonous (or possibly deadly), so thanks - do you think I still should?
And thanks for the photos of the blue-green agros from Mexico - those actually resemble the pins and slightly larger of the species I've found. In The Eastern US where I am it dries out fairly quickly, and I think that that causes a color change plus cracking. I will water and such the beds where they are popping up by the twenties to see if I can get a few that look blue/green or whatever into a more mature state.

Yeah mine are shrinking, but not really losing any moisture..in fact they seem to be more so, almost slimy, but not so much to lose the mushroom shape. They also seem to get darker/bluer(?) so I thought it was like some kind of bruising..

Bluing is obvious. You will most likely know when you see it.
