Description: The habitat of this small epiphytic lichen is the leathery leaves (especially the leaf midrib) of certain ornamental trees and shrubs, especially box and Rhododendron. The green granular crustose thallus produces tiny flat to convex discs (0.1–0.16mm diam.) sometimes effused with an orange pigment. The spores number 8–16 in the ascus, one-septate and fusiform. In Ireland, the species is known from County Down.

Key Identification Features:

• Thallus granular at first, becoming thicker with age; discs flat then convex, numerous
• Spores to 16/ascus, one-septate, spindle-shaped.
