Excipulum 0.13-0.28 mm diam., Well-developed and obconical, or rather poorly-developed as a short collar around base of mazaedium, consisting of periclinally arranged, ± branched hyphae. Hypothecium broadly obconical to semiglobose, with convex upper surface. Capitulum with a dense yellow pruina on lower side of excipulum. Asci cylindrical, with well-developed stalk, 12-20 × 1.9-2.7 µm, produced singly and with uniseriate spores. Ascospores spherical to broadly ellipsoid, 3.1-7.7 × 2.5-3.6 µm, ± provided with irregular cracks giving rise to an irregular ornamentation.
