Ecology: Biotroph; lichenicolous; endosubstratic. Host or Phorophyte Taxonomy: Chondropsis semiviridis.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Perithecioid, subglobose (subglobose to broadly ellipsoid), forming inside the thallus or mycelium of the host, not emerging, (85)-100-120-(130) µm wide, (105)-115-135-(155) µm high, with a dark brown surface. Margin: Brown, (6)-8-14-(15) µm wide; external filaments absent. Disk: Smooth. Exciple: Paraplectenchymatous (textura angularis); hyphae (5)-7-9-(13) µm wide, 2-3 µm long; brown. Hymenium: Iodine reaction: Lugol’s negative. Interascal Hyphae: Present, distinctly branched, distinctly anastomosed; cells 1.5-2 µm wide.

Asci: Broadly clavate, distinctly stipitate (short-stalked), 44-64 µm long, 12.5-13 µm wide; ocular chamber present; dehiscence bitunicate (fissitunicate); exoascus not amyloid; ascoplasm dextrinoid.

Ascospores: Uniseriate (ovgerlapping), c. 4 per ascus, spores 4 per ascus, ellipsoid or pyriform, (14)-17-19.7-20-(21) µm long, (6)-6.5-6.8-7.5-(8) µm wide, obtuse; septa present; transversally septate, 1-transversally septate; lumina apically enlarged, constricted at the centre; wall thick (with gelatinous sheath), distinctly differentiated into primary and secondary wall (with gelatinous sheath), laterally constricted where the septum meets the spore wall, becoming pigmented, middle brown (deep yellow-brown), not ornamented (with gelatinous sheath).
