A cyanolichen characterized by bluish grey, squamulose isidiate thallus formed on conspicuous prothallus. It typically grows on mossy bark of old deciduous trees in moist microhabitats (e.g. in old-growth forests). Rarely, it also occurs on mossy rocks. Parmeliella triptophylla is one of the suboceanic lichens linked in Central Europe to humid mountain ranges with minimal air pollution. In the past, this species was repeatedly reported from Czech mountains (see catalogue Vězda & Liška 1999). However, it has disappeared from most of its original localities. Recent records come only from the Šumava Mts (corries of lakes, Modrava, Ždanidla).
