Nigrograna puerensis

Ciri dan struktur

Saprobic on decaying branch of Coffea arabica. Sexual morph: Ascomata 90–180 µm high, 90–150 μm wide (x̄ = 138 × 115 μm, n = 10), immersed, with only ostiolar necks visible on the host surface or erumpent, solitary, subglobose to ellipsoid, dark brown (#6e5031). Peridium 10–15 μm wide (x̄ = 13 μm, n = 15), outer layer consists of 2–3 layers of textura prismatica, brown (#937463) and thick-walled cells, inner layer hyaline with thin-walled cells. Hamathecium composed of numerous, 1.5–2 µm wide (x̄ = 1.8 μm, n = 20), filamentous, hyaline, septate, pseudoparaphyse. Asci 50–80 × 8–11 μm (x̄ = 66 × 9.5 μm, n = 20), 8-spored, bitunicate, fissitunicate, cylindrical to clavate, short pedicellate, apically rounded, with poorly developed ocular chamber. Ascospores 15–18 × 4–5 μm, (x̄ = 16 × 4.5 μm, n = 30), uni- to bi-seriately arranged, fusoid, apical cell and basal cell acute, and apical cell slightly wider than basal cell, straight or slightly curved, 1-septate, constricted at septum, guttulate, hyaline to yellow-brownish (#daceb8) when young, brownish (#937463) when mature. Asexual morph: Undetermined. On PDA, colonies reached up to 4 cm diam. after two months at room temperature (22–26 °C). Colony dense, circular, slightly raised at the center, surface with white aerial mycelium, fluffy, with a serrate edge, grayish (#c9bfb3) to dark brown (#6e5031) from center to edge, reverse dark green (#3a4543) to dark brown (#6e5031).
