I cannot discern

the micro features very well.
Do the hyphae have clamps? Are they monomitic, dimitic, trimitic, pseudodimitic?
Methinks I have seen some thickwalled. Do you have seen basidia?
Some of the photos I think show something like a hyphomycete. Maybe just conidial stage? Or infected? Any cystidia? Are these basidiospores or conidiospores?
I do not think it’s Byssocorticium as mentioned.
The probability this being undescribed is relatively high as in Corticiaceae this is often the case, especially in “exotic” countries like Mexico. Isn’t it dangerous doing research there?

I looked into Byssocorticium and I am not sure that the spore shape matches. Most of those seem to have tear dropped shaped spores, not elliptical.

only the first two would be left to consider. I do not know Porostereum crassum, but Byssocorticium would be a possibility although the color of the fruitbody does not really match (should be more greenish than purplish).
Besides, from the micro pics it seems to me that there are also conidiospores present.
It somehow reminds me of Hypochnella violacea but just superficially.
