LICHALP

Sarcogyne regularis Körb. var. psimmythina (Nyl.) N.S. Golubk.

Syn.: Lecanora psimmythina Nyl.

Lichenised. Poorly known taxon.

Substrate: intermediate rocks (such as calciferous schists)

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: a variety with a thin white thallus and black, marginate apothecia, based on a type from Finland; on micaschists; not consistently distinguished, and distributional data therefore incomplete and hard to interpret.
