I am not sure what type of cystidia this is. Maybe pleurocystidia. The next picture shows the context of where it was found.

So I guess this turned out to be ovoideocystidiata after all?

Any updates?

I’m curious as to why this was thought to be a new species?

Psilocybe ovoideocystidiata is an Eastern, USA species correct.

Alan, any macro pics of blue staining?

yea

It does look a lot like that collection. I will soon have some samples from that find to make a herbarium deposit and compare the dna and microscopy.

Hmm…

Reminds me of something you have checked about two years ago…

I do not think it is ovoideocystidata

The cystidia are very different – Ovoideocystiata has abundant cystidia and they are rare in this species. Also the shapes are very different. Pileipellis is probably different. Ovoideocystidiata has a lot of cheilocystidia and it is rare in this species.
