LICHALP

Koerberia biformis A. Massal.

Lichenised.

Substrate: bark

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: a mild-temperate species found on rough bark, mostly of old deciduous trees, especially Castanea and Quercus, in humid areas; apparently more frequent in the Western and Southern Alps, but never common.
