Amphithecium: cortex distinct, gelatinous, containing large crystals insoluble in KOH. Epihymenium brown, with coarse granules soluble in KOH, 5-10 µm tall. Hymenium hyaline, 50-60 µm tall, paraphyses simple, slightly thickened at the tip. Hypothecium hyaline, 50-90 µm thick. Ascospores simple, hyaline, 7.5-12.5 x 4.5-7.5 µm (Lü et al. 2009: 438).

Photobiont: Data lacking.

Chemistry: Atranorin, gangaleoidin (Lü et al. 2009: 438) and other publications.

Ecology: Corticolous, on bark and twigs.
