SUMMARY
Mycelium immersed, not staining in iodine.
Anamorph: conidiomata pycnidia, 150–200 μm diam., the wall brown below and greenish brown above, K– or K+ green. Conidiogenous cells 7–14 × 4.5–5 μm. Conidia (6–) 6.5–8.5 (–10.5) × (3.5–) 4–5 (–6) μm, ellipsoidal with a truncate base, hyaline, aseptate, verruculose.
Teleomorph: ascomata (110–)180–290(–400) μm diam. and (80–)110–170(–220) μm tall, superficial, blackish, often with a yellowish pruina, UV–, subglobose, with a strongly convex disc and a strongly constricted base. Hymenium hyaline to pale greenish brown, K– (becoming green in the upper part from epihymenial pigment), N–, I–, K/I–, 50–85 μm tall (including the epihymenium); epihymenium dark greenish brown, K+ green and N+ purplish brown, 13–20 μm thick. Hypothecium dark brown, K–, N–. Exciple absent. Interascal tissue of branched and anastomosed paraphyses 2.5–3 μm diam. Asci 55–65 × 12–15 μm, clavate, thick-walled, I–, K/I–, 8-spored. Ascospores (12–) 13–16.5 (–20) × 5–6 (–7) mm, brown, verruculose, 1-septate, the upper cell usually slightly shorter and broader than the lower cell.
