This eye-catching epiphyte is usually sterile (the brown-black discs are rare), yet even in this state it has a distinctive appearance owing to the blue-green granular-isidiate thallus seen growing between and among tree bark mosses. It occurs in coastal woodlands of oceanic areas especially on oak. In Ireland, it occurs mostly in the west where it is local.
