Syn.: Alyxoria diaphora (Ach.) Gray, Alyxoria notha (Ach.) Gray, Opegrapha chlorina Pers., Opegrapha cymbiformis Flörke, Opegrapha diaphora (Ach.) Ach., Opegrapha lichenoides Pers., Opegrapha notha Ach., Opegrapha pulicaris auct. p.p. non Pers. ex Fr., Opegrapha rimalis Pers., Opegrapha varia Pers., Opegrapha varia Pers. var. fagicola A.

Lichenised.

Substrate: bark, lignum

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a mainly temperate lichen found on old trees in humid but rather open forests, occasionally on basic siliceous rocks in humid and shaded situations. The delimitation of this species is still an open problem: here it is still treated as a collective taxon.
