Anisomeridium ranunculosporum (Coppins & P. James) Coppins
Syn.: Arthopyrenia ranunculospora Coppins & P. James
Lichenised.
Substrate: bark
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: this species is peculiar in the shape of the one-septate ascospores with the lower cell much longer than the upper one; thalli with macroconidiomata only are difficult to identify; on smooth bark in old-growth broad-leaved forests; perhaps overlooked but certainly rare in the Alps, more common in extra-Alpine Europe.
