Confirmed P. adiastola in specimen

You can’t see it in the photos, unfortunately, but what’s happened here is that this lichen nearly died recently. There are extensive blackened areas just back from the lobe tips. Then it recovered and fresh lobes started growing out of the blackened parts. These conditions tend to induce the soredia to start growing out into full-on lobes and thalli themselves. That’s why the soredia look extra coarse and almost “moss-like”.

P.adiastola means sorediate… I’ve looked for soredia and think that in some places what looks like soredia in fact could be (?) parts of mosses that the lichen overgrow. Nothing green here as P.adiastola should have. Never saw apotecia on P.adiastola, but always on P.ciliata. However I first time see P.ciliata not on a hardwood bark but on mossy rock. I remeber a key where it was for Phaeophyscia: apotecia ciliate – P.ciliata
