This is the commonest of the three Irish representatives of this mainly tropical genus. In T. lepadinum the raised discs resemble barnacle-like warts scattered over a shiny, pale, grey-cream crust. It can be found mostly on the smooth bark of trees where there is a history of continuous canopy cover, but can also spread to rock.
