I received a sample of some of these fungi and other more by TAK. Just observe the spores and do not correspond with the type of P. naematoliformis, these fungi also have chrysocystidia as some species of Deconica or Hypholoma.

That and spore samples of each observation if possible.

It’s entirely possible that these are Psilocybe as obs. 20163 is, but I know a similar looking species of Deconica does grow in this area. I have specimens myself from _ obs. 77107_. I am getting some immersion oil type A in the mail soon, so I will put some spores up from that observation for comparison.

Alonso – Sometimes this species stains blue at the base, most the time it does not though.

Christine – I just recently got a scope, but check out the work sporeworks did on my collections of this Psilocybe species from a few years ago.

You can see it here.

Do you have any microscopic images you could share for this observation?
