Acarospora chrysocardia Poelt & M. Steiner

Lichenised.
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: on base-rich siliceous rocks, growing on the thalli of Diploschistes scruposus below the subalpine belt; hitherto known only from dry-warm valleys of the Western Alps and Catalonia, and certainly worthy of protection.
Switzerland: Valais; Italy: Piemonte; Valle d'Aosta;
