Sutton & Beaumont, 1989: Widely recorded and often common in all five vice-counties. Generally most frequent away from industrial areas although it now occurs regularly on the outskirts of Leeds where lichens are still much affected by air pollution. It has also recently been found quite commonly just to the west of Sheffield (D. Whiteley per JP).
2012 (CHF): Now common and widespread across all five vice-counties and like most members of this genus, increasing in numbers.
