Pertusaria trochiscea Norman

Lichenised.

Substrate: living mosses, plant debris

Altitudinal distribution: subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a species resembling P. glomerata, but with a different secondary chemistry (coronaton), thallus reacting K-, and 4-spored asci; on bryophytes and plant debris, with scattered records in Northern Europe from the subarctic to the boreal-alpine zone, rarely recorded elsewhere, with a few records from the Eastern Alps (Austria).
