Saprobic on wood, Sexual morph: Ascomata 300–450 pm diam., subglobose, immersed, ostiolate, papillate, coriaceous, cream–coloured, single. Necks 250–800 µm long, 80–115 µm wide, ostiolar canal filled with periphyses. Peridium 20–27 µm thick, composed of about 6 layers of polygonal cells, forming a textura angularis, merging with the thin–walled pseudoparenchymatous cells. Catenophyses developing from the pseudoparenchyma that originally fills the central cavity. Asci 70–95 x 25–35 µm, 8–spored, clavate, pedunculate, rounded at the top, without a pore, non–amyloid, thin–walled, unitunicate, more or less persistent, maturing successively on an ascogenous tissue at the bottom of the locule. Ascospores 12.5–16.0 µm, subglobose, one–celled, hyaline, containing one large lipid body staining a deep blue in Sudan Black B surrounded by numerous small non–lipoid droplets with a single, top–shaped appendage. Appendages 4–5 µm high, 6.5–8 µm diam., unfurling in water to form tapering ribbons, 250–550 µm long, 1.5–3 µm wide, staining blue in methylene and cotton blue.
