I have hundreds of micrographs of this species that I will upload when I get to California. I will take a close look at them.

I think they are conspecific. To check this you would have to review and study the holotype and comparing the two species. For now will study their collections deposited in the Fungal Collection of the Institute of Ecology, Xalapa.

Thanks for taking a look at these!

Do you think this taxon could be conspecific with P. muliercula?
