Ciri dan struktur
Saprobic on decaying wood of Fagaceae. Sexual morph: Ascomata 586–690 × 425–630 μm (x̄ = 638 × 527 µm, n = 5), scattered, solitary, mostly superficial, unilocular, globose to subglobose, covered with dense dark brown setae (2–6 μm wide), dark brown to black, coriaceous, ostiolate. Ostiole central, wide, with a pore-like opening visible on the host, orange to yellow. Peridium 54–69 μm wide, multilayered, heavily pigmented, comprising 13–16 layers, hyaline to dark brown cells of textura angularis to textura prismatica. Hamathecium comprising 1.5–3.3 μm wide, dense, septate, filiform, branching pseudoparaphyses, embedded in a gelatinous matrix. Asci 115–146 × 9–12 μm (x̄ = 127 × 10 μm, n = 20), 8-spored, bitunicate, fissitunicate, cylindrical to clavate, apically rounded, with a well-developed ocular chamber, long pedicellate (46–53 μm long). Ascospores 31.6–37.6 × 6–7.6 μm (x̄ = 34 × 7 μm, n = 20), biseriate, overlapping, oblong fusiform, hyaline to pale brown, tapering towards both ends, smooth-walled, slightly curved, 1-septate, constricted at the septa, without mucilaginous sheath. Asexual morph: Undetermined. Single ascospores germinate on MEA within 24 h. Colonies on MEA, fast growing, full plate within one week at 25 °C, medium dense, convex, velvety with white aerial mycelium, entire, reverse dark orange, pale yellow at margin. Orange pigmentation diffused into the media.
