It could well be

It could well be one of the crustose lichens but difficult to tell from this photo, and as you say, there are rather a lot of yellow crustose lichens to choose from!

You don't say if you were able to look at yours with a hand lens, but if you are you may find that you can see the thallus more clearly and perhaps even find tiny apothecia, all of which help towards discovering its identity.
