Anamorph: unknown. Teleomorph: ascomata 35-80 x 5-8 mm, cylindric-clavate to narrowly clavate, often somewhat laterally compressed, the apex obtuse, black (glossy when fully hydrated). Fertile part not clearly differentiated from the stipe, occupying the upper part of the ascoma and extending to around one third of its length. Stipe 1.5-3.5 mm diam., terete, dark brown to fuliginous, not viscid, minutely furfuraceous or rugulose. Interascal tissue composed of filiform paraphyses 3-4 µm diam., longer than the asci and not strongly adherent, not curved or coiled at the apex, rather thin-walled, pale brown throughout, not closely septate and not or slightly constricted at septa below, the apical cells varied in form, usually slightly enlarged, narrowly clavate to pyriform, the terminal cell sometimes globose. Asci 140-180 x 15-18 µm, cylindric-clavate to clavate, mostly slightly attenuated towards the rounded apex, fairly thick-walled but not fissitunicate, with a J+ apical pore, 8-spored. Ascospores arranged in parallel, 60-80 x 4.5-6 µm, straight or somewhat curved, narrowly cylindric-clavate with a rounded apex and tapering obtuse base, dark brown early in development, almost always 7-septate, fairly thick- and smooth-walled, without a gelatinous sheath or appendages.
