Anamorph: unknown.

Teleomorph: Stromata absent. Ascomata 550-700µm diam, often slightly flattened, with a long cylindrical neck to 1000µm in length, black, immersed in the substratum, thick-walled, covered in narrow flexuous yellow-brown hyphae. Peridium composed of several layers of dark brown fairly thick-walled textura angularis, the neck constructed of similar cells. Interascal tissue of copious trabeculate pseudoparaphyses. Asci 210-240 x 18-25µm, ± cylindrical, fairly short-stalked, the apex obtuse, 8-spored. Ascospores arranged obliquely uniseriately to biseriately, 36-41 x 21-27.5 x 16-19µm, roughly fusiform overall, with a strongly oblique septum, strongly constricted at the septum and ? sometimes fragmenting at maturity, very thick-walled, the germ slits straight, narrow, with a thick gelatinous sheath.
