Thallus effuse, composed of small green granules up to 50 µm diam., at first scattered but soon coalescing to form a thicker thallus. Photobiont cells 7-12(-15) µm diam.

Anamorph: not known.

Teleomorph: ascomata apothecial. Apothecia usually abundant, 0.1-0.16 mm, disc rounded, flat when young but soon becoming convex to hemispherical, sometimes contiguous and fused in well-developed specimens, pale to orange, becoming brown in old specimens. Exciple only visible in young apothecia. Epithecium and hypothecium colourless. Paraphyses abundant only in young apothecia, simple or furcate and rarely anastomosing.
