Description: This large, foliose lichen forms spreading rosettes (to 15cm diam.) on well-illuminated, siliceous cliff ledges by the sea. It is closely related to N. loxodes and N. verruculifera but unlike those species lacks isidia. Its nearest lookalike is N. delisei which is pale coffee-brown in colour. N. pulla may be told by the wrinkled lobes and abundant discs but most importantly by the grey-brown to dark brown colour. Local. Throughout Ireland.

Key Identification Features:

• Non-isidiate thallus on acid rock
• Thallus colour: pale, coffee-brown; in grey lichen zone of sea cliffs.
