Syn.: Placynthium subradiatum (Nyl.) Arnold f. anemoideum Servít
Lichenised. Poorly known taxon.
Substrate:
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 a blackish crustose thallus composed of subsquamulose, roundish areoles (not effigurate at the margin), with sessile, black apothecia and one-septate ascospores, based on a type from Croatia; on calcareous rocks, ecology poorly known but in the protologue contact to running water is not indicated; the only record from the Alps (France) needs critical re-evaluation.
