Syn.: Biatorella elegans (A. Massal.) Stizenb., Biatorella monasteriensis (J. Lahm ex Körb.) J. Lahm, Biatoridium elegans (A. Massal.) Reinke, Chiliospora elegans A. Massal.

Lichenised.

Substrate: bark, lignum

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 mild-temperate lichen found on deciduous trees with base-rich bark (Acer, Fraxinus, Sambucus); much overlooked in the past, but locally not infrequent on Sambucus along brooks, and widespread throughout the Alps.
