Ciri dan struktur

Saprobic on dead fronds of a fern, without dark superficial hyphae, appearing as black dots on host surface. Sexual morph Ascomata 40–60 µm high, 55–75 µm diam., immersed in host tissue, becoming erumpent, solitary, subglobose to globose, dark brown, uni-loculate, glabrous, ostiolate, with minute papilla. Peridium 3–10 µm wide, thin-walled, composed of 2–5 layers of flattened, brown pseudoparenchymatous cells of textura angularis. Asci 30–50 × (10–)12–15(–19) µm (\(\bar{x} \) = 41.5 × 13.6 µm, n = 30), 8-spored, bitunicate, ovoid to ampulliform, short pedicellate, with an ocular chamber. Ascospores (15–)17–20(–22) × (3–)4–5(–6) µm (\(\bar{x} \) = 18.6 × 4.7 µm, n = 30), overlapping 2–3-seriate, hyaline, ellipsoidal to fusiform, inconspicuously 3-septate, not constricted at the septa, narrowly round at the ends, sometimes curved at the middle, with a guttule in each cell. Asexual morph Undetermined. Culture characteristics: Colonies on PDA reaching 34–36 mm diam. after 3 weeks at 20–25 °C, colonies circular, dense, flat, slightly raised, surface dull, with edge entire, woolly to velvety; from above, dark grey at the margin, white-grey at the centre, separating from the margin by convex, concentric ring; from below dark greenish at the margin, with green yellowish at the centre; not producing pigmentation in agar.

Saprobic on dead fronds of a fern, without dark superficial hyphae, appearing as black dots on host surface. Sexual morph Ascomata 40–60 µm high, 55–75 µm diam., immersed in host tissue, becoming erumpent, solitary, subglobose to globose, dark brown, uni-loculate, glabrous, ostiolate, with minute papilla. Peridium 3–10 µm wide, thin-walled, composed of 2–5 layers of flattened, brown pseudoparenchymatous cells of textura angularis. Asci 30–50 × (10–)12–15(–19) µm (\(\bar{x} \) = 41.5 × 13.6 µm, n = 30), 8-spored, bitunicate, ovoid to ampulliform, short pedicellate, with an ocular chamber.
