This ‘dog lichen’ is an uncommon species of mossy tree trunks and fallen timber. The blue-grey or brown thallus is characterised by numerous marginal lobules and a relatively smooth, upper surface. The underside will be seen to have narrow, white, raised veins. In Ireland, the species is known from County Kerry and from one mossy boulder in County Londonderry.
