Amandinea pelidna (Ach.) Fryday & Arcadia

Syn.: Amandinea lecideina (H. Mayrhofer & Poelt) Scheid. & H. Mayrhofer, Biatora pelidna (Ach.) Rabenh., Lecidea lygaea Ach. f. pelidna (Ach.) Ach., Lecidea pelidna Ach., Rinodina lecideina H. Mayrhofer & Poelt

Lichenised. Poorly known taxon.

Substrate: siliceous rocks

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: this species differs from A. punctata in the median spore wall thickening, the rimose thallus, and perhaps in the frequent presence of pycnidia. The typical form is apparently a coloniser of siliceous boulders and outcrops near the seashore (type from a lowland locality in Ireland), and the identity of records from the Alps, treated as “orophilous ecotype” by Roux et coll. (2017), requires further critical study.
