LICHALP

Psorotichia tiroliensis Zahlbr.

Syn.: Porocyphus arnoldii (Heufl. ex Arnold) Arnold, Psorotichia arnoldii Heufl. ex Arnold

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: similar to Porocyphus coccodes, but with 16-spored asci; the generic placement is in need of re-evaluation, and the ecology is poorly documented as well; known from a few localities in the Alps.
