Anamorph: not known. Teleomorph: ascomata apothecia, very strongly cupulate and appearing perithecial, 350-500 × 300-400 μm, ovoid to obpyriform, pale yellow. Peridium hairy, with cells 10-22(-25) × (5-)9-14(-16) μm., angular to irregularly shaped, mostly thick-walled. Hairs to ca 120 µm in length and 6-12 µm diam., shorter (15-30 µm long) around the apex, hyaline, thick-walled, cylindric or slightly tapered, the apex obtuse, often without a lumen, becoming more flexuous below, simple or branched at the base, the wall 1.5-2.5(-3.0) μm thick, often thickest towards the base and becoming thinner towards the apex, with scattered, thin septa. Interascal tissue of paraphyses 2.5–3.5 μm diam. at the base, often branched near the base, slightly tapering towards the rounded apex, sparsely septate. Asci (110-)120-150(-180) × 18-20(-29) μm, clavate to cylindrical, short-stalked, thin-walled and not fissitunicate, the apex rounded, without apical structures, not blueing in iodine, 8-spored. Ascospores uniseriate or irregularly biseriate, 30-41(-45) × 12.5-17 μm, broadly fusiform, often slightly asymmetric, aseptate, hyaline, containing one or two guttules, the spore wall slightly thickened at both ends, smooth, without a gelatinous sheath or appendages.
