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 thin, spreading, ochraceous, finally rimose-areolate thallus, immersed to subsessile perithecia (to 0.5 mm in diam.) covered by a thalline layer, and broadly ellipsoid to subglobose ascospores (to c. 25 µm long or even longer); on metamorphic schists, only known from the type locality in the Western Alps (Switzerland).
