Anamorph: Acrogenospora sp. Conidiomata absent. Conidiophores 250-400 µm high, 12 µm wide at the base narrowing to 8 µm at the apex, 3- to 11-septate, scattered or in clusters, erect, straight, unbranched, thick-walled, smooth, septate, red-brown, tapering towards the apex, not synnematous. Conidiogenous cells integrated, terminal, monoblastic, percurrent, annellate, red-brown becoming very pale towards the apex. Conidia 22-36 x 17-28 µm, globose to broadly ellipsoidal, with a protruberant truncate base at the point of attachment, thick-walled, smooth, simple, red-brown, solitary.
Teleomorph: Ascomata 0.5-2 x 0.25-0.3 mm, hysterothecial, elongate, narrowly ellipsoidal to fusiform and straight to irregularly curved from above, with a conspicuous involute longitudinal slit, black, smooth, superficial, scattered to gregarious or rarely crowded, in no particular alignment. Peridium 60-70 µm thick, the side walls composed of polygonal dark brown-walled cells at the exterior but becoming elongate-prismatic towards the interior, basal region similar, with a layer of compressed hyaline cells forming the floor of the cavity. Interascal tissue composed of filiform paraphysoids 1.5-2 µm diam. Asci 80-110 x 14-20 µm, cylindric-clavate, short-stalked, thick-walled, fissitunicate, J-, 8-spored, arising parallel from the floor of the cavity. Ascospores 20-26 x 8.5-12 µm, irregularly ovoid with one side ± straight, smooth, 1-septate, constricted at the submedian septum, one cell very large and red-brown, the other cell minute (about 3 µm long) and hyaline.
