I’ve only looked at specimens without inspersed oil drops, so seeing what they actually look like is great.
I uploaded a photo with a comparison of two specimens, one with hymenium clear (just one that I’m analyzing now and serves as one with perfect transparent hymenium) and the one in this observation that serves an (extreme, say) example of one with hymenium inspersed. Of course, rarely you find such extreme cases and there are all intermediates between the two cases. If you have further doubts, please ask me. This character of the hymenium (clear vs inspersed) is not only used in Buellia but also in other genera of lichens. The case I know better in of the genus Graphis, where it is a very important character with taxonomical value.
Do you have photos of this? I don’t have any context for what this looks like in the hymenium.
