This large, shiny, brown to dark brown, foliose lichen with lashings of coarse isidia scattered over the surface like grit, appears to be predominantly coastal in Ireland. Discs when present have isidiate margins. N. pulla, N. loxodes and N. delisei (all described elsewhere) are lookalikes. N. pulla is paler, has extensively wrinkled lobes and no isidia and is often found with discs. N. loxodes is also paler and has isidia, but these are present in discrete piles on the lobes with non-isidiate lobes between. N. delisei is like N. pulla but is a paler, golden-brown. Well-illuminated acid rock.

Key characteristics

  • Large (growing to the size of an adultís hand), dark brown thallus with abundant, coarse isidia
  • On well-lit siliceous rocks, coastal and inland.
