LICHALP

Rinodina parasitica H. Mayrhofer & Poelt

Syn.: Rinodina milvina (Wahlenb.) Th. Fr. var. amphibolitica Räsänen

Lichenised.

Substrate: , siliceous 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: an arctic-alpine species found on siliceous rocks in upland areas, often growing on the thalli of other crustose lichens; easy to overlook and certainly more widespread in the Alps.
