Sexual morph: saprobic, ascomata: 270-675 µm high, 570-1080 µm broad, gregarious, immersed, deep seated, subglobose-ellipsoidal, ostiole with long neck extended to the surface of the wood, neck aperiphysate. Surrounding and bordering the ascomata there is a brown transitional zone 20-30-60 µm thick in which the substrate cells are not easily discernible. Peridium: 2-layered, an outer layer 16-20 µm at the base, thinning towards the apical region, consisting of hyaline, prismatic, nearly isodimetric cells (4-8 µm in diam.); an inner layer 60 µm thick at the base of the ascomata and again thinning out towards the neck region, composed of long, thin-walled often pointed cells, 20-40 x 8-10 µm, which are longer and broader towards the base of the ostiole. Melanisation of the outer peridial cells of old ascomata commences in the neck region and extend around the ascomata. Necks: up to 1500 µm long, 46-76µ m in diam. cylindrical, brown-black; outer layer of the neck 8-16 µm thick, consisting of slender prismatic cells (2-3 x 4-8 µm) merging with the hyaline small-celled tissue which forms the ostiolar channel. Asci: 90-140 x 24-28 µm, 8-spored, clavate, tapering, pedunculate, unitunicate, thin-walled, early deliquescing, in different stages of maturity in a hymenium on a sub-hymenial layer formed as a broad, flat cushion or a flat cup in the lower part of the ascomata cavity, interthecial filaments present. Paraphyses: absent. Ascospores: 19-24 x 8-10 µm, 1-septate, hyaline, ellipsoidal or broadly fusiform, slightly constricted around septum, hyaline, released in masses into ascomata cavity before emerging through neck, surrounded by a mucilaginous sheath, bounded by the delimiting membrane, which is constricted at the septum. Appendages: spores are enveloped in a granular sheath with polar appendages at either end which appear as outgrowths of the spore wall; polar appendages initially short (ca 28 µm) then becoming long and drawn out sometimes forming fine threads; the sheath and polar appendages swell in water to form a diffuse mass, are extremely sticky and adhere to substrata; the sheath is slightly constricted at the septum with radiating striations extending from the spore wall (Description based on Jones & Koch (1986)).
