Altitudinal distribution: subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a species with a reddish-white, rather thick, areolate thallus (not showing any reaction), apothecia (0.4-0.8 mm in diam.) immersed in the thallus, usually 1 per areole, hymenium exceeding 150 μm in height, large 8-spored asci, and broadly ellipsoid ascospores (15-24 × 12-16 μm); on siliceous rocks (granite); only known from the type locality in the Eastern Alps (Switzerland).
