Lecanora coppinsiarum, a new Tasmanian lichen related to Lecanora symmicta

The new species Lecanora coppinsiarum Kantvilas is described, based on collections from Tasmania. It is characterized by an entirely sorediate thallus containing atranorin only, and the anatomy of its biatorine apothecia, its Lecanora-type asci and small, hyaline, simple ascospores suggest a relationship to L. symmicta (Ach.) Ach. The South American species L. subviridis de la Rosa & Messuti is recorded for the first time for Tasmania.
