Syn.: Porina meliospila (Nyl.) Zahlbr., Porina taylorii (Carroll ex Nyl.) Swinscow, Verrucaria meliospila Nyl., Verrucaria taylorii Carroll ex Nyl.

Lichenised.

Substrate: bark, calciferous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a species with 1-septate, easily fragmenting ascospores, differing from S. brevis only in the longer (to c. 18 µm long) macroconidia; on bark of broad-leaved deciduous trees (especially Quercus, Alnus, Fraxinus, Juglans) in humid-shaded situations, occasionally also on limestone; widespread in Mediterranean and especially Atlantic Europe, and also known from Macaronesia; probably more widespread in the Alps, but largely overlooked.
