Yes. Both the mushroom and the mycelium may bruise blue when damaged.
Not all Psilocybes bruise blue, however this one does.

Thanks for all these helpful comments, Shane.
This was the only fruiting body I could find in the area and as you can see it is pretty small, But I did see some pretty turquoise looking mycelia, nearby. Does the mycelium stain blue in the these or other Psilocybes?

last couple years as it was making its “arrival”, it was mostly found in San Fransisco, and looks much like a Cyan, hence the coined name “Cyanofriscosa”
however, this year people in washington state have been reporting it growing.

im no expert but ide say the range is probably from santa cruz california to seattle washington.

ive seen specimens in santa cruz as far back as 05, and there was just a report of this growing in san jose.

what is the current range of this yet to be named mushroom?

The term “Cyanofriscosa” was coined for these, but they have yet to be named.
They appear to have the macroscopic features of P.Cyanofibrillosa, yet spore studies on these have shown that they have the same spore characteristics as P.Cyanescens, only they are much larger.

I’m interested to see when these are going to be named.
