concerning the genus. I think this is again Nephroma laevigatum. I quickly performed the K-reaction on medulla and the result was exactly the same as in MO77853. Thanks, Jason, for the correction.

You might consider Nephroma helveticum

The lower surface looks brownish, which would be off for Leptogium (should either be same color to slightly paler than upper surface, or densely white tomentose, but never brownish).
