Amphithecium (thalline excipulum): Present; 50-65-75-(80) µm wide; crystals small, abundant, dissolving in 10% KOH; photobiont abundant. Amphithecial Cortex: Absent, indistinct, pseudocortical, 15-20-25-(30) µm wide, basally widened, 30-40-45 µm wide at the base; inspersed with oil droplets. Episamma: Soluble in KOH. Epithecium: Apical cells slightly swollen, hyaline or dark brown, soluble in 10% KOH. Hymenium: Not inspers. Hypothecium: White; not inspers.

Ascospores: c. 8 per ascus, broadly ellipsoid, 8.5-10-11.5-(12) µm long, 4.5-5.5-6.5-(7) µm wide; wall thin, not ornamented.
