Lower Surface: Present, black, black in the centre, brown along the margin; attached by holdfasts; not cyphellate; not wrinkled; rhizinate; rhizines moderately abundant, with a narrow non-rhizinate margin or with a broad non-rhizinate margin, black, not branched; not tuberculate.

Hydrochasic Thallus Movement: Not performing hygrochasic thallus movement.

Upper Cortex: Double-layered.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, forming all across the thallus surface, all across the surface, sparse. Margin: Smooth, epruinose; not sorediate; not isidiate; without pseudocyphellae pseudocyphellae; not ciliate; not hirsute. Disk: Brown. Hymenium: 70-75-80 µm high.
