Description: Lecanora zosterae can appear to resemble L. dispersa growing on decaying sea-cliff plants, especially, thrift (Armeria maritima), low-growing grasses or dead or dying plant stems. Essentially, the lichen thallus is hidden, so the species occurs as a scatter of tiny, short-stalked, unevenly shaped discs (to 3mm diam.) with thin white margins and red-brown centres. Records are scattered, coastal southern Ireland and west Donegal; probably more widespread.

Key Identification Features:

• Thallus inapparent; discs like L. dispersa but irregular-shaped and short-stalked with darker centres
• On sea cliffs: dead thrift cushions or wild thyme stems, moribund grasses, etc.
