On CMA with sterile rice seeds, hyphae branched, septate, hyaline to brown, smooth, 2–4.5 μm diam. Conidiophores solitary, erect, unbranched, subcylindrical, straight or curved, medium brown, thick-walled, smooth, 5–10-septate, 95–200 × 8–13.5 μm. Conidiogenous cells integrated, terminal, medium brown, smooth, 30–45 × 5–7.5 μm, forming a rachis with several protruding denticles, 2–3.5 × 2–4.5 μm, and a minute marginal frill. Conidia solitary, obclavate, guttulate, 3-septate, smooth, unequally colored, with brown median cells, olivaceous to subhyaline apical and basal cell, 45–65 × 8–10.5 μm; hilum truncate, slightly protruding, with marginal frill, unthickened, not darkened, 2–3 μm diam; apex tapering, subacutely rounded, with a mucoid cap, 3–5 μm diam. Sexual state unknown.

Colonies on PDA 9 cm diam after 7 days at 25 °C in dark; surface flat, transparent with dark mouse-grey areas; reverse with dark spots. Colonies on MEA 5 cm diam after 7 days at 25 °C in dark; aerial mycelium, white, mouse-grey in center, raised, cottony, round; reverse dark mouse-grey in center. Colonies on CMA and OA 9 cm diam after 7 days at 25 °C in dark; surface transparent, with thin, spreading mycelium with scattered dark spots of sporulation (Colony description from Klaubauf et al., 2014).
