Etymology.

Referring to the long, hyaline ascospores.

Description.

Epiphytic on the upper surface decaying leaves, appearing as small black dots. Covering the upper leaf surface with dark mycelium without penetrating host tissues. Mycelial pellicle elongate, subiculum-like, comprising hyphae that are mostly narrow, dense, dark brown. Mycelial setae broad, dark brown, scattered, discrete, arranged as a ring around the pellicle, unbranched, formed on dense, dark hyphae. Sexual morph: Ascomata superficial, solitary, dark brown to black, globose to subglobose, coriaceous, uni-locular, somewhat flattened when dry, covered by a mycelial pellicle. Peridium pale brown to brown, with compressed, hyaline, inner cells of textura angularis and dark brown outer cells of textura angularis, fusing and indistinguishable from the host tissues. Asci 8-spored, bitunicate, broadly obovoid, slightly stalked, apically rounded, with a well-developed ocular chamber. Ascospores overlapping, irregularly triseriate, hyaline, fusiform, elongated, multi-septate, slightly constricted at the septa, tapering to the ends, smooth-walled, surrounded by a thin mucilaginous sheath. Asexual morph: Not observed.
