These specimens are very similar, either macro and micro, to others posted before from the same location. As before there are two strong candidates for its classification within the genus Protoparmelia: P. badia and P. montagnei. It seems that the main difference between the two species consists in the spore form, more fusiform with acute ends in the former and more ellipsoid with rounded ends for the latter, and some subtle chemistry, which is of less value since some morphs are known for the latter species.
One of my favorites websites actually presents photos of the spores for the two species mentioned above, available at the following links:
Comparing those with my own observations I conclude that the spores can not be classified as fusiform with acute end (at least as clearly as at the first link above), being more probably better described as ellipsoid. Their dimensions fall in the ranges 8-10.4 × 2.3-2.9 µm. Therefore, the species should be P. montagnei.
