LICHALP

Caloplaca macrocarpa (Anzi) Zahlbr.

Syn.: ?Caloplaca alpigena Poelt ined., Placodium aurantiacum (Lightf.) Anzi var. macrocarpon Anzi, Variospora macrocarpa (Anzi) Arup, Søchting & Frödén

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 alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a species of the C. dalmatica-group with a thallus of dispersed areoles in shades of orange, partly covered by sessile, relatively large (c. 1 mm in diam.), orange-red apothecia with persistent, paler margins; on subhorizontal rock faces and rocky heads at high elevations; widespread in the Alps but regionally undercollected. According to Vondrák (see Nimis 2016), however, at least the material called C. macrocarpa by Poelt and Hafellner (GZU) belongs to a different species.
