Notes: The macro features and the chemistry of this specimen seem to point to Arthonia pruinata or to a close species, due to less pruina. The form (Arthonia type) and the opening of the asci by a slit-like rupture also agrees with the description given in CNALH for the genus Arthonia, but their sizes (33-57 × 24-36) as well as those of the spores (average Me = 27.5 × 10.7 µm ; Qe = 2.6 (N=9)) are very different than mentioned there for Arthonia pruinata. So, what is this?
