Chaenotheca laevigata Nádv.

Lichenised.
Substrate: bark
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a cool-temperate to southern boreal-montane lichen found in bark fissures of acid-barked deciduous and coniferous trees in humid forests, more rarely on lignum; probably overlooked and more widespread, but certainly never common in the Alps.
Austria: Vorarlberg; Salzburg; Steiermark; Niederösterreich (incl. Wien); Switzerland: Schwyz; France: Alpes-Maritimes; Italy: Trentino Alto Adige;
