Apothecia sessile, 0.3–0.7 mm diam.; disc dark orange-brown to red-brown, epruinose or slightly grey-pruinose; margin concolorous with the thallus, thin, verruculose. Cortex hyaline, inspersed with small crystals, 10–30 µm thick laterally and basally. Amphithecium with large crystals insoluble in KOH (pulicaris-type). Parathecium hyaline, 15 µm thick, with numerous small crystals insoluble in KOH. Epihymenium reddish brown, c. 10–15 µm thick, with numerous small crystals (pulicaris-type); pigmentation and crystals soluble in KOH. Hymenium, subhymenium and hypothecium hyaline.
