Hi Marland

You had me confused for a moment! Doing a bit of continent hopping for Christmas?

Candelariella vitellina usually comes with a granular crust and there doesn't appear to be much of a thallus here. It might be a Caloplaca (K+ crimson vs no reaction with Candelariella) - possibly the C. holocarpa group. Let's hope someone more knowledgeable about these two genera stops by.

Yes - glad to see you here

Already got quite a few pics to put up - was hoping to be able to name some first - but not as easy as one thinks.
Also wondering how popular I'd be if I started putting chemicals on walls and trees in London.
