Sexual morph: saprobic, Ascomata: 75-112 µm in diam., globose or slightly flattened, coriaceous, white-light buff, gregarious, light coloured, free (attached to the wood by a few or several thick-walled sinuous hyphae 4 um in width), or embedded in the outer few layers of the substratum. Ascomata with numerous appendages and lacking an ostiole. Appendages 4-8 µm high, 2-3 µm broad at the base, the stem dividing into 2-3 (-6) tapering blunt branches. Peridium: membranous, with one wall layer, 1-2 cells thick, cells flat and angular up to 12 µm in diam. Asci: 8-spored, in a hymenium arising from a small, flat cushion of pseudoparenchymatous cells at the base of the ascomata, claviforme to cylindrical, pedunculate, persistent, and lacking an apical apparatus. On release from the ascocarp, asci expand becoming broadly claviform to oblong spherical, 68-147 x 28-57 µm with the cytoplasm or spore cluster occupying only a minor part of the ascus. Ascus tip appears granulated or viscous. Ascospores released as a cluster through a broad circular opening of the ascus tip. Ascus wall elastic and sometimes bulging from the side or tip, persistent after spore release. Paraphyses: absent. Ascospores: unequally 2- (-4) celled, 10-16 x 6-9 µm, strongly constricted at the septum, hyaline, with a uniform mucilaginous sheath. Asexual morph: undetermined (Description based on Koch & Jones (1989)).
