Delitschia palmietensis K.D. Hyde & Steinke
Etymology: from the Palmiet River
Saprobic on submerged branch. Sexual morph: Ascomata 310–420 μm high, 310–430 μm in diam, irregularly subglobose, subglobose or oval, brown to black, immersed or semi-immersed, coriaceous, papillate. Papilla central, erumpent or partially embedded, covered in a light brown tomentum, periphysate. Peridium 20–30 μm wide, comprising several layers of hyaline angular cells, external layers of cells with brown walls. Pseudoparaphyses 2–3 μm in diam, hypha-like, filamentous, septate, numerous, highly branched and anastomosing above the asci. Asci 200–250 × 10–12 μm, 8-spored, cylindrical, fissitunicate, pedicellate, with an ocular chamber and faint ring. Ascospores 30–35 μm, overlapping uniseriate, fusiform, dark brown, 1-septate, strongly constricted at the septum, forming part-spores in some, surrounded by a thin mucilaginous sheath. Asexual morph: Undetermined.
