Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a calcicolous species with a spreading, olive-brown, subrimose thallus, semi-immersed ascomata (to c. 0.4 mm in diam.) covered by a thin thalline layer, an adpressed involucrellum reaching down about half of the perithecium, and ellipsoid ascospores (to 30 µm long); only known from the type locality in the Western Alps (Switzerland), and from Liguria (outside the Alps).
