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-grey, rimose to areolate thallus, immersed perithecia with a descending involucrellum, and ascospores with highly variable septation (partly simple, partly with 2-5 transversal septa, and partly with an incomplete longitudinal septum); on periodically inundated siliceous rocks in the European mountains, with a single record from the Eastern Alps (Austria).
