Commonly known in English as blushing rock tripe and ombilicaire virginale in French, Swales encountered this lichen "on rocks with slight flow of water over them, near top of mountain" while travelling through Harrington Harbour in the Côte-Nord region of Quebec in July 1964. The lichen Swales encountered that summer has a distinct pinkish tinge on the lower surface that would have helped her identify it as blushing rock tripe. 

Known to favour rocky surfaces, this member of the Umbilicariaceae family can be found across boreal and arctic regions.
