LICHALP

Lecidea aemulans (Arnold) Britzelm.

Syn.: Lecidella aemulans Arnold

Lichenised.

Substrate: calciferous 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: a calcicolous species of unclear relationship, as the paraphyses are given as conglutinated and the ascospores are relatively slim, provisionally placed here in Lecidea s.lat.; reported from the Alps, the Tatra Mnts., and Spitsbergen, with optimum near or above treeline.
