In Africa, Peccania tiruncula has been recorded from Algeria, Morocco, Namibia, and the Sahara; in the Arabian Peninsula, it is found in Oman. In 2016, it was noted to occur in Turkey; collections from this country were noted to grow alongside other lichens Synalissa symphorea and Psorotichia schaereri. Peccania tiruncula is also found in Europe and North America.[4] It often grows in calcareous rocky habitats.[5]
