Lecidella carpathica Körb.

Description: This crustose lichen has a well-developed, grey-green, cushion-like thallus more granular and verrucose than in L. stigmatea with which it is usually compared. A section through the disc base (hypothecium) shows it as bright orange-brown in K. In L. stigmatea the hypothecium is colourless to pale yellow-brown. On weakly basic, slightly nutrient-enriched rock: wall tops, asbestos cement roofs. Counties Kerry and Galway.

Key Identification Features:

  • Thallus grey-green, more cushion-like than in L. stigmatea; discs black, red-brown within, orange-brown in K along the hypothecium; overlooked
  • Slightly basic, nutrient-enriched rock.
