Lecanora coppinsiarum, a new Tasmanian lichen related to Lecanora symmicta

The new species <em>Lecanora coppinsiarum</em> 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 <em>Lecanora</em>-type asci and small, hyaline, simple ascospores suggest a relationship to <em>L. symmicta</em> (Ach.) Ach. The South American species <em>L. subviridis</em> de la Rosa & Messuti is recorded for the first time for Tasmania.
