Is this what I think it is? Chlorociboria species, "green elfcup"

Is this pscilocibin? It seems characteristic of that blue green color and besides some algaes I don't know anything else natural in that color. Is this a fungi rich in pscilocibin? I'd assume maybe this is the mycelium?

Maybe, inedible "blue stain fungi"?

Nope, that's one of the Chlorociboria species, commonly known as "green elfcup". It won't make you high, but if you find a piece of the substrate wood that's still somewhat hard you can make some really nice craft stuff with it. The colour is very persistent and light-tolerant. Cool stuff. Here's a picture of a simple pendant I made with it years ago. Love the contrasts between the green, black and wood-coloured areas.

Wow so cool. I had no idea. I may carve into it and see if I can find some solid wood that color. Thank you!

I did some more research on blue green elf cup and I have to say the pictures of these mushrooms and the mycelium filled wood are magical, straight out of avatar! Haha. Thank you for your help! I hope to see the fruits soon!
