The taxonomic position of this fungus is uncertain. Stromata are discoid, with sloped margins, subepidermally erumpent, and probably with bipartite stromata, 1.5-3 mm diam x 1 mm thick, black externally and internally, carbonaceous. Perithecia are ovoid, 0.3-0.4 mm diam x 0.8 mm high. Ostioles are lower than the stromatal surface, and have punctate openings. Asci are possibly bitunicate, clavate, short-stipitate, with eight ascospores arranged in a partially biseriate manner, with an inamyloid apical crown. Ascospores are dark brown, unicellular, ellipsoid, nearly equilateral, 42-55 x 23.5-32.5 mm, with a straight, spore-length germ slit and a hyaline sheath. Miller (1961) considered this fungus to be a typical Nummularia.
