They look like dried panaoelous cyanescens, aka "pan cyans". Those are god-tier mushrooms. They are much more potent than any psilocybe strain. Their psilocin to mass ratio is much higher, and has a higher concentration of other tryptamine alkaloids, including some not present in "regular" 'shrooms. Pan cyans are known for producing more vivid trips, require much smaller doses to ingest, taste less like ass, and are less likely to induce indigestion. They're not common among distributors because flush yields are smaller and not often suitable for profitable sale. The teks for growing are also different, costlier, and more involved. They also need to be more delicately dried in order to retain potency. Mostly only hardcore hobbyists or psychonauts grow or seek them out. I had a spore syringe of the species once but never did grow them. Something I regret; not many vendors stock their spores, and those that do usually only intermittently. Edited for editing.
