Could be

P. leprosa is getting to be an annoyance for me. This looks to be the sort of thing I try to call P. leprosa, but whenever I try to confirm it with a bleach (C) test, I turn out to be wrong. In fact, though evidently common in some areas, it is quite localised.

In the absence of apothecia or evidence of a positive C test, I would slightly favour it being a scruffy Lepraria. But until I find P. leprosa myself, I am not qualified to comment.
