Thallus apparently absent, presumably not lichenized. Anamorph: not observed in this study. Conidia rod-shaped, 3-5 × 1-1.5 µm (Coppins & Orange 2009). Teleomorph: ascomata perithecia, formed below an involucrellum, rather variable in shape but usually ± circular, oblate to shallowly conical in section, only very shallowly domed, the ostiole sometimes weakly papillate. Involucrellum (350-) 400-600 µm diam., to 50 µm thick, composed of heavily melanized and occluded ± epidermoid tissue, fused with the upper peridium except at the edges of the ascoma, sometimes extending beyond the ascoma by 20-30 µm. Ostiole quite broad, lined with periphyses ca 10 µm long and 2 µm diam. Peridium 8-12 µm thick, composed of tissue intermediate between epidermoid and hyphal in structure, the cells 2-3 µm diam., dark brown in both upper and lower parts. Interascal tissue composed of rather thick-walled closely septate pseudoparaphyses 2-2.5 µm diam., branching not observed (? due to poor preservation of the specimen). Asci 86-102 x 20-25.5 µm, clavate, with a fairly short tapering stalk, the apex rounded, thick-walled and presumably fissitunicate, the apical wall not noticeably thickened and without a distinct ocular chamber, (4-) 8-spored. Ascospores arranged biseriately, 23-27.5 x 8-10 µm, ellipsoidal to fusiform-ellipsoidal, sometimes slightly ovoid, 3- to 5-septate, the lumina tending to be rounded, hyaline, rather thick-walled, smooth, surrounded by a narrow gelatinous sheath.
