MycoBank number: MB 121607; Index Fungorum number: IF 121607; Facesoffungi number: FoF 10041; Fig. 58

Isolated from soil. Sexual morph: Ascomata 280–620 µm (x̄ = 480 µm, n = 10) diam., perithecial, gregarious, superficial, globose to subglobose, brown to black, carbonaceous, verrucose, ostiolate, with papilla, periphysate. Peridium 60–100 µm (x̄ = 75 µm, n = 20) wide, comprising two layers, outer layer carbonaceous, composed of black cells; inner layer membranaceous, composed of pale brown to hyaline cells of textura angularis to textura prismatica. Paraphyses numerous, filiform, evanescent. Asci (170–)190–250(–280) × 13–17 µm (x̄ = 225 × 16 µm, n = 20), 8-spored, unitunicate, cylindrical, pedicellate, apex rounded, with subapical globule, evanescent. Ascospores bi-seriate, slightly curved, aseptate, multi-guttulate, hyaline and ellipsoidal when young, becoming multi-septate, geniculate, 2/3 upper cells swelling, truncate at the base, dark brown when mature, 30–35(–45) × 4–7 µm (x̄ = 34 × 5.5 µm, n = 50); 1/3 lower cells hyaline when mature, 12–18(–20) × 4–6 µm (x̄ = 15 × 4.5 µm, n = 50), smooth-walled, with bipolar short conical appendages (upper cauda 3.5–5.5 × 1–2.5 µm; lower cauda 6.5–10 × 1.5–3 µm), disappearing with age. Asexual morph: Hyphomycetous, phialophora-like. Conidia small, oval to globose (adapted from von Höhnel 1917).
