Description: Currently known only from east Mayo, look for this small lichen growing in the crevices of elder (Sambucus) bark. The thallus is thin, green, and powdery and the spherical discs (perithecia) pale brown and rather well hidden. The spores are one- to three-septate (12–20µm long) and shaped like an elongated ellipse.

Key Identification Features:

• Thallus like a thin, green Lepraria crust growing in the crevices of elder bark
• Perithecia pale brown with one- to three-septate spores.
