The clue to finding this lichen is to search out its habitat in damp, humid oceanic woodlands which are trees such as birch, sallow and holly, ringed with thick cushions of leafy liverworts of genera such as Scapania and Plagiochila. The tough, black, shiny pin-like discs project from the liverworts like a golf-tee-shaped submarine periscope. In Ireland, the species is known only from County Kerry.
