Description: This green, shrubby species of exposed, siliceous maritime rocks and cliffs is to be found growing with shaggy colonies of sea ivory (Ramalina siliquosa) which dominate such habitats. R. subfarinacea is not unlike R. farinacea (described elsewhere) in appearance and in having soralia. It differs in that the soralia are more untidy — like skin sores, turning K + yellow to red, and the soredia more granular in texture. The entire plant is generally spikier than R. farinacea would ever be.

Key Identification Features:

• Occurring with sea ivory colonies on exposed cliffs
• Like Ramalina farinacea but spikier and with soralia (which produce powdery soredia), rather deep-seated and turning K+ yellow to red.
