(the areoles with a minutely verruculose surface), hemispherically protruding ascomata (to 0.2 mm in diam.) mostly arising inbetween or at the edges of the areoles, an involucrellum adpressed to the perithecial wall and reaching down about half of the perithecia, and oblong to ellipsoid ascospores (to c. 15 µm long); only known from the type locality at the base of the Western Alps (Italy).
