The 'Before' and 'After'? No: two Different Lichens

We were wondering whether the Lichens in this picture viz.

are the 'Before' (the lower Lichens) and the 'After' (the upper Lichens) .

Well: seemingly Not.

Opinion suggests that [i] the lower Lichens are probably a Lecanora sp. (possibly L. albella, L. chlarotera or L. hypocarba) and [ii] that the upper Lichens might be a Lecidella sp. (possibly L. elaechroma) or perhaps Buellia erubescens?

Providing Confirmation, not that it was ever needed, that to become even a Novice Lichencologist, one needs a 'Big Brain'.

And it possible that the Hint of Yellow in the upper Lichen might be a developing Xanthoria parietina?
