the rhizines seem to be as you described, simple not forked; therefore, Parmelina is more likely for the genus; On the other hand, I can see no alternative to P. tiliacea.

In my opinion it is Parmeliaceae, probably Parmelina, speaking about the lobes, for me they are round, Hypotrachyna is different.
It has isidia. It’s intricated with Parmelia saxatilis, and a bit old, so I don’t see the central isidia, however, P. quercina or P. carporrhizans are not isidiate (right?) and they have apothecia, and P. pastelifera has button isidia. Remains the common P. tiliacea that I don’t find :)P

the lobes have more square-cut tips than is common in Parmelina, where the lobes are more roundish. In addition, soredia (or isidia?) is on small amount and restricted to some lobes; P. tiliacea is commonly covered by coralloid isidia, or at least the center of thallus.

Why not Parmelina and why Hypotrachina?
