LICHALP

Buellia fusca (Anzi) Kernst.

Syn.: Buellia spuria (Schaer.) Anzi var. fusca Anzi

Lichenised. Poorly known taxon.

Substrate: siliceous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)

Note: on vertical to underhanging surfaces of siliceous rocks near the ground in warm-dry situations, such as in arid grasslands and in openings of Mediterranean garrigues; known only from the Eastern and Western Alps, and the Pyrenees. Related to B. tyrolensis, but chemically different, this taxon needs further study.
