Sexual morph: Ascomata 170–280 μm high, 230–330 μm diam., scattered, solitary, or in groups, semi-immersed to erumpent, visible as raised, black dot on the host surface, globose to subglobose, occasionally irregular in shape, uni-loculate, glabrous, ostiole central, with minute, mammiform papilla, lacking periphyses. Peridium 15–40 μm wide, of unequal thickness, composed of several layers, of small, flattened to broad, pseudoparenchymatous cells; outer layer comprising brown to dark brown cells of textura angularis; inner layer comprising flattened, hyaline cells of textura angularis to textura prismatica. Hamathecium composed of numerous, 2–5.5 μm wide, filamentous, septate, anastomosed pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci (67–)80–110(–132) × (13–)16–20(–24) μm (x̅= 98 × 18.8 lm, n = 25), 8-spored, bitunicate, fissitunicate, broadly cylindrical to cylindricclavate, or clavate, short pedicellate, with truncate pedicel, apically rounded, with inconspicuous ocular chamber, clearly seen when immature. Ascospores (12–)14–18(–20)(–23) × (4–)5–8(–13) μm (x̅ = 17 × 7.7 lm, n = 50), overlapping 1–2-seriate, dark brown, muriform, fusiform to ellipsoidal, with acute or rounded ends, or acute at the upper cells, asymmetrical, slightly larger in the upper part, straight, sometimes bent, mostly 4–6 transverse septa, with 1–2 longitudinal septa in each cell, becoming many sectors, constricted at the central septum, smooth-walled, lacking a mucilaginous sheath. Asexual morph: Undetermined.

 

Culture characteristics: Colonies on PDA reaching 28–30 mm diam. after 1 week at room temperature (20–30 ºC). Colony medium dense, circular, flattened, surface smooth, with edge entire, velvety to woolly; from above, white to cream at the margin towards the centre, with sectored, greenish grey to dull green or light green at the centre; from below, cream to pale yellowish at the margin, yellowish at the middle, brown-green at the centre; not producing pigmentation on agar medium.
