Candelariella aurella can also grow on wood

But it has a granular or undeveloped thallus. C. vitellina definitely has a thallus that looks like this. You must be right. Let’s go with it.

I don’t have a specimen for this one,

but the only one I can think of is C. vitellina – I think that can grow on wood, and generally similar in appearance.

This looks more like Candelariella to me

The small round bits of thallus scattered about, and the crowded mounded apothecia seem more typical for Candelariella than Caloplaca. Also, Thomson shows no species of Caloplaca on wood with yellow thallus (C. flavorubescens can, as you showed a little while ago, but it is a thin “stain” not well-developed discrete round areoles like this).

On stairs’ handrail.
