P. bolliana – C-, pseudocyphellae inconspicuous, very wrinkled, on bark
P. hypoleucites – C+r, conidia 8-18µm, almost exclusively on bark
P. graminicola – C+r, conidia 4-10µm, on bark or (usually) rock
I’m having trouble finding morphological differences between the three. Bruce Ryans calls hypoleucites “±rugose or reticulately ridged” with apothecial margins pseudocyphellate. But it doesn’t mention lack or presence of these characters in graminicola (= semansiana). But it ddoes say that apothecia are abundant in graminicola.
I’m not willing to venture a guess without chemistry and conidia measurement, since all three are well-documented in your area (according to CNALH). We need to build up a better set of observations with solid determinations based on chemistry and microscopy, I think. I would be surprised if there are no subtle morphological clues. But I don’t know what they are yet.
