Anamorph: conidiomata to 600 µm diam., solitary or aggregated in clusters of up to five or more, immersed, partially erumpent when mature, dark brown to black, irregular in shape but mostly ± globose. Ostiole central, circular, minutely papillate. Conidiophores absent. Conidiogenous cells (11−) 12–15 × 4–5 μm, ± cylindrical, hyaline, smooth, proliferating percurrently and sometimes annellate, the proliferation often inconspicuous. Conidia (20−) 21.5–25.5 (–27.5) × (9.5−) 12–14 (−15.5) μm, ± cylindrical to ovoid, straight, both ends broadly rounded, hyaline, aseptate, smooth, fairly thick-walled, without a gelatinous sheath. Teleomorph: Ascostromata to 300 μm diam., unilocular, solitary or clustered, immersed, partially erumpent when mature, ± globose, dark brown to black, thick-walled, the wall composed of an outer layer of thick-walled dark brown angular cells, and an inner layers of thin-walled hyaline angular cells. Ostiole central, circular, minutely papillate, periphysate. Interascal tissue absent. Asci 100–160 × 14–22 μm, clavate, long-stalked, thick-walled and fissitunicate with a well-developed ocular chamber, not staining in iodine, 8-spored. Ascospores biseriately arranged, (25–) 28–35 (–36) × (9.5–) 10–12.5 (–13.5) μm, ellipsoidal to ellipsoidal fusiform, sometimes slightly curved, both ends rounded, hyaline, thin-walled, smooth, aseptate, rarely becoming light
brown with age.
