Lichenised.
Substrate: bark
Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a temperate, perhaps holarctic species found on isolated deciduous trees, not uncommon in orchards. The basionym is often cited as “J. Lahm ex Körb.”, but Körber explicitly attributes the species to Lahm (“Lahm in litt. ad Kbr.”). See also note C. sarcopisioides.
