LICHALP

Psorotichia lugubris (A. Massal.) Arnold

Syn.: Stenhammara lugubris A. Massal.

Lichenised. Poorly known taxon.

Substrate: calciferous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: perhaps related to P. murorum, but with a verruculose to squamulose thallus and inconspicuous apothecia which are first immersed, later prominent, and somewhat wider ascospores; on calcareous rocks; overall distribution poorly known, with a few scattered records from the Alps.
