Description

Sexual morph: Ascomata 590–740 µm in diameter, 840–1020 µm high (x̅ = 660 × 864 µm, n = 10), black, solitary or gregarious, globose to subglobose, uniloculate, coriaceous to carbonaceous, superficial, with a short neck and central ostiole, periphysate. Peridium 95–125 µm wide, reddish brown to dark brown, comprising outer thick layers of textura angularis, and inner layers of prosenchymatous or elongate cells. Paraphyses 4.5–9 µm wide, hyaline, unbranched, septate, constricted at the septa and tapering. Asci 125–220 × 15–21 µm (x̅ = 175.5 × 18.3 µm, n = 20), 8-spored, short pedicellate, apex flattened, with a J-, subapical ring. Ascospores 28–45 × 6–11 µm (x̅ = 37.6 × 7.6 µm, n = 30), biseriate, brown, falcate to lunate, or ellipsoid, 4-septate, verrucose, apical cell appendaged, basal cell pointed and hyaline. Asexual morph: Hyphomycetous. Cultures grow well on PDA and MEA, forming greenish to dark brown colonies. Mycelium composed of branched, septate, hyaline to brown hyphae. Conidiophores macronematous, mononematous, erect, pale brown to brown, pale toward the apex, straight or flexuous, smooth. Conidiogenous cells 5.5–12 × 2–4 µm (x̅ = 8.6 × 3.1 µm, n = 32), enteroblastic, monophialidic, integrated on hyphae, terminal, sometimes erect on hyphae, pale brown, subcylindrical, ampulliform. Conidia 3–5.5 × 1.5–3.5 µm (x̅ = 4 × 2.6 µm, n = 80), unicellular, hyaline, fusoid-ellipsoid, obovoid or ellipsoid, obtuse or broadly rounded at apex, tapering to a truncate base, smooth-walled.

Culture conditions: Colonies on PDA reached about 15 mm diameter after 21 days at 25°C.
