Description: The thallus of this crustose epiphyte is thin, smooth and grey. The discs are piebald, pink or brown, sessile, convex and often clustered. It grows on base-rich bark in shaded woodland and belongs to an epiphytic lichen community in which species of nutrient-rich bark do not feature. L. cyrtella, is similar, but that species is a plant of nutrient-rich bark habitat. In Ireland, L. cyrtellina has been recorded from Counties Fermanagh and Armagh.

Key Identification Features:

• Thallus grey, thin and smooth with sessile, convex, orange-pink-brown closely grouped discs
• On non-enriched basic-barked trees.
