From Liang et al. (2010) “Two new unusual Leucoagaricus species (Agaricaceae) from tropical China with blue-green staining reactions” Mycologia 102(5):1141-52 (http://www.mycologia.org/cgi/content/abstract/09-021v1): “It is possible that there might be psilocin and psilocybin in the bluing species of Lepiota (Stamets 1996), or in our case Leucoagaricus, but no chemical analysis has been carried out.”

Thanks Dave!

I’m kicking myself for not saving this mushroom. I collected one, but I left it in the bag and maggots destroyed it before I dried it out. The entire mushroom (what was left of it) was starting to turn blue today when I pitched it.

I wonder if the bluing is psilocybin/psilocin related.

the blue staining on the annulus. Didn’t know what to make of it. Kuo documents this species.
