Anamorph: not known. Teleomorph: ascomata apothecia, 0.4-0.8 mm diam., at first immersed, opening broadly by a pore but not becoming erumpent, the margin narrow, strongly white-pruinose, entire to lacerate, the disc deeply urceolate, pale ochraceous. Margin in cross section 40-70 µm thick, 3-layered, often with a poorly differentiated accessory thalline margin, the wall 20 µm thick, of closely-packed cells 1.5-2.5 µm diam., hyaline, the crystalline layer moderately well-developed, of heterogeneous non-rosettiform crystals. Periphysoids 10-20 x 1.5-2 µm, septate, unbranched, not gelatinized. Subhymenium ca 10 µm thick, of small hyaline angular cells, J-. Interascal tissue of paraphyses, numerous, filiform, ca 1 µm diam. below, barely enlarged above, unbranched or sparingly branched, J- or faintly J+. Asci 130-200 x 6-8 µm, the cap 2.5-3 µm thick, pierced by a narrow, conical pore, 8-spored. Ascospores fasciculate, not or hardly helically coiled, 130-200 x 1.5-2.5 µm, filiform, septate, the cells 3-5 µm long, without an epispore or gelatinous sheath.
