At present this lichen is restricted to the Welsh coast and south-west England, but the range once extended into central England and along the coast to Kent. A population also occurred in the Firth of Clyde (2). In Europe, the distribution is Mediterranean-Atlantic, the northern extreme of which is in Anglesey. Elsewhere this lichen becomes widespread in tropical and the warmer temperate areas of the world (2) (8).
