This rare species of Ramalina is easily overlooked for R. farinacea (described elsewhere), with which it often grows. It has hollow, twisted branches that are both swollen and smooth-textured often with terminal lip-shaped soralia that are K+ red. It is a species of sunny, sheltered coastal sites of south-west and western Ireland where it grows mainly on tree trunks and more rarely among rocks, heather and scrub near the sea.

Key characteristics

  • Like R. farinacea in size and shape but has more contorted branches with inflated, hollow stems
  • It tends to have terminal soralia that are K+ red (mainly K- in R. farinacea).
