Description: This is a not uncommon lichen of vertical, calcareous sea-cliff crevices. The species is likely under-recorded in Ireland as there are only records for Counties Cork, Clare, Donegal, Dublin and Down. It has the typical features of L. hutchinsiae (described elsewhere) except that the discs turn translucent and brown-speckled when wet.

Key Identification Features:

• Like L. hutchinsiae but always with flatter discs which are translucent and brown speckled when wet
• Crevices and underhangs of calcareous sea cliffs.
