Three crustose lichens

I’m struggling with these three crustose lichens because they are so small and no matter how I’ve tried I can’t get better pictures and so are probably unidentifiable.
At the top and bottom are two patches of white crustose lichen, the lower patch measures 7mm x 19mm, the apothecia appear as black ‘scribbles’; the nearest I’ve found to this is Opegraphia atra.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Oops! It's a plum tree.

I think I've spent too long looking at descriptions of likely matching lichens and I totally forgot to tell you what the tree was. My apologies. Belatedly, it is a plum tree.

Thank you for the correct identification.
