Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a calcicolous species recalling (in section) V. muralis, but with smaller ascospores, characterised by a thin, rimose, dirty-whitish thallus, conically to hemispherically protruding ascomata (to c. 0.25 mm in diam.) with a thick, adpressed involucrellum reaching down about a third of the perithecium, and ellipsoid to oblong ascospores (to c. 20 µm long); known from a few scattered records in Europe, including the Eastern Alps (Austria).
