Description: This is a foliose species that is a common sight on sunny siliceous rocks and boulders. The shiny dark brown colour of the upper surface of the isidia-smothered lobes distinguishes it from subsp. glabratula which is primarily a paler coloured lichen of trees rather than rock.

Key Identification Features:

• A distinctive dark brown, low, leafy lichen of granitic rocks and boulders;
• Medulla C+ red; isidia on the lobes plentiful.
