Lecidea atrobrunnea (DC.) Schaer. subsp. atrobrunnea

Syn.: Lecidea funckii Flot., Lecidea protecta H. Magn., Lecidella atrobrunnea (DC.) Körb., Psora atrobrunnea (DC.) A. Massal., Sporastatia funckii (Flot.) Dalla Torre & Sarnth.

Lichenised.

Substrate: siliceous rocks, calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a bipolar, arctic-alpine to boreal-montane species of acid siliceous rocks in exposed situations, starting the life-cycle on species of Bellemerea or on L. silacea, with optimum near and above treeline. The species is chemically variable, and several chemotypes were distinguished; widespread throughout the Alps.
