Hi Alan,

Yes, Psilocybe cyanescens is known to be a west coast species. That was the basis of my experiment actually. I wanted to see if I could introduce a non-native species to a relatively similar environment. The mycelium was planted in a patch in the woods last Fall. It seems to have survived the Winter, Spring
and Summer in Massachusetts and happily popped its head up this Fall. Experiment successful!

I’m curious now as to why we don’t see this species more often on the East coast. You would think that the spores, over time, would be dispersed on the East coast from air currents and the like. Hmm.

Maybe cyanescens

Psilocybe cyanescens is more of a west coast species. Unless you have verified that these are Psilocybe cyanescens using a microscope, these are very likely to be a different active Psilocybe species. Psilocybe caerulipes is one species that is known from that area and likes to fruit in the late fall. Psilocybe ovoideocystidiata is another possibility though it has not been recorded from that state. If your mushrooms have a slight annulus near the middle of the stipe it is probably that species. It would be helpful to know the shape and size of the spores.
