Saprobic on woody substrates, Sexual morph: Ascomata: up to 260 μm high, 351-450 μm diam., perithecioid, immersed, depressed globose or almost conical, mostly with flattened base, carbonaceous, ostiolate, with a neck and arising mostly singly. Necks: black, short, raised, seen as a black column on the host surface with a cylindrical almost slit-like opening, 78-150 μm high, 130-176 μm in diam. (above the host surface), periphysate, comprised of small dark compact cells.   Peridium: up to 15 μm thick, brown, at the inside comprised of thick-walled hyaline compressed cells, brown and angular toward the middle and a confused highly melanised textura igantean towards the outside. Hamathecium:  hyaline, hyphae-like, unbranched, numerous, septate, weakly tapering, up to 3 μm wide, fused at the base and sides of the ascomata and joined at the top with the periphyses and upper wall. Asci: 112-148 x 19.6-25.5 μm, forming from the sides and base of ascomata, 8-spored, clavate, bitunicate, fissitunicate, pedunculate and with an ocular chamber and non-amyloid ring. Ascospores: 28-39.2 x 7-9.8 μm , 2-3 seriate, 2-celled, fusiform constricted at the septum, hyaline, surrounded by a narrow mucilaginous sheath which is drawn out at the poles to form tapering appendages, 6-8 um long.  Asexual morph: Undetermined.
