Description: Irish records for this species emanate from north Kerry, County Waterford and west Galway, which suggests it was possibly confused with L. ochroidea which is primarily a species of vertical, siliceous coastal rocks and told by its grey cracked thallus and white-frosted discs. In this respect it can resemble L. rupicola, but that species has more compressed, immersed, C+ yellow discs. L. ochroidea has discs C- but is noted for its K+ yellow-red thallus. 1 L. subcarnea is C-, K- and grows away from the coast on base-rich rocks often in dry cliff recesses by loughs.

Key Identification Features:

• L. subcarnea: grey cracked thallus and discs white, frosted; discs C-, thallus K-, outcrops by loughs
• L. ochroidea: grey cracked thallus and discs white, frosted; discs C-, thallus K+ yellow-red, siliceous sea cliffs.
