definitely azurescens…

i can attest to that. ;)
as far as the ecological role…
“biological terrorism” comes to mind.

I don’t have accurate answers for you, Herb. I do know that they’ve been found almost a mile from several of the patches, so there is evidence of colonization by sporulation. I believe the cultivator began introducing this species at least 5 years ago. I am not sure which, if any native Psilocybe species can be found in WI. I imagine there is potential for natural occurrence of semilanceata, quebecensis, ovoideocystidiata and caerulipes.

As far as which native species may suffer from the introduction of this highly aggressive invasive species, whose to say? I could see many Marasmiaceae and Mycenaceae being out-competed for resources.

Very interesting

How far away from the original inoculation point are they found now, and what year was the inoculation? What are some of local species growing in the same habitat that have a potential to be displaced? Do you find any other native Psilocybe species in the same area? Thank you.

Photographed these while foraging with a friend in northern WI. This, and several other Psilocybe species were introduced to the wild with inoculated spawn. Azurescens in particular is apparently quite prolific in Wisconsin’s boreal woods; it now occurs in areas that were not treated with inoculate.

Do you have any other info to go along with this observation? How did you come to your determination?

I’d say

It’s safe to assume it’s an introduced invasive species at this point. I wonder what impact that will have on the local ecology in a couple hundred years?

found growing in the wild or was this from someone’s planted patch?
