Description

Saprobic on dead segment of Elaeis guineensis. Sexual morph: Ascomata 120–210 × 170–260 μm (x̄ = 155.4 × 219.6 μm, n = 15), immersed to erumpent, visible as black dots on host surface, solitary to scattered, with a central ostiole, coriaceous, subglobose, unilocular. Ostiole central. Peridium 15–25 µm wide (x̅ = 19.8 µm, n = 20), hyaline to brown, comprising several layers of textura angularis cells, thinner-walled and lighter to the inner side, outside fusing with the host. Hamathecium 1–2 µm wide (x̅ = 1.3 µm, n = 20), pseudoparaphyses, embedded in a gelatinous matrix. Asci 65–95 × 6–8.5 μm (x̄ = 79o.6 × 7.2 μm, n = 20), bitunicate, fssitunicate, cylindrical, 8-spored, hyaline, apically rounded, with a short pedicel. Ascospores 17–25 × 2.5–5 μm (x̄ = 21.2 × 3.7 μm, n = 20), overlapping 1–2-seriate, fusiform and tapering to both ends, hyaline, 1-septate, constricted at septum, guttulate, smooth-walled. Asexual morph: Not observed.

 

Culture conditions: Colonies on PDA after 2 weeks reaching 5–6 cm diam., at 25 °C, circular, flat, filiform margin, with white aerial mycelium, floccose, above white to greyish green, reverse pale yellow to greenish.
