Description

Saprobic on dead leaflets and rachides of Cocos nucifera (Arecaceae). Sexual morph Ascomata 150–330 μm diam., solitary or gregarious, immersed, visible as black dots on substrate, with an ostioler or papilla, in vertical section 210–320 μm diam., 190–220 μm high, subglobose or globose, with a rounded or flattened base, coriaceous. Ostiole central, periphysate. Peridium 9–18 µm wide, consisting of several layers of cells of textura angularis, outside layers brown cells and inter layers hyaline, thinner at the base. Paraphyses 2–3 µm wide, hypha-like, irregular, septate paraphyses, rarely branched. Asci 78–110 × 6–12 µm (x̅ = 94.2 × 9 µm, n = 20), 8-spored, unitunicate, cylindrical, pedicellate, thin-walled, with a J+ wedge-shaped, subapical ring, 2–2.5 µm diam., 1 µm high. Ascospores 10–15 × 4.5–6 µm, (x̅ = 12.7 × 5.4 µm, n = 50), uniseriate, ellipsoidal, aseptate, pale brown to brown, with a central pallid band, smooth-walled, without appendages and sheath. Asexual morph Undetermined.

 

Culture conditions: colonies on MEA reach a diam. of 20mm after three weeks at 25–28˚C.
