Saprobic on decomposing leaf of an unidentified angiosperm. Sexual morph: undetermined. Asexual morph: Conidiomata straw-coloured, stromatic, cornuted to spuriously synnematoid, solitary to gregarious, erect or variously curved, slightly roughened, differentiated into a stalk and a conidiiferous head; stalk 1.5–2 mm long, 100–300 µm wide, subcylindric, slightly swollen at the base, becoming narrowed above, head 200–300 µm diam., 150–200 µm high, ellipsoidal to subcylindrical, often with a pointed tip, with the concave conidial intricate; excipulum of hyaline, textura porrecta; hymenium of textura prismatica to textura angularis. Conidiophores hyaline, septate, branched, smooth-walled, with up to 3 terminal conidiogenous cells or sterile hyphae, arising in cavity of conidiomata. Sterile hyphae hyaline, clavate to subcylindrical, with an obtuse apex, straight or curved, septate, smooth-walled. Conidiogenous cells 10–25 × 2–3 µm, hyaline, cylindrical to subcylindrical, discrete or integrated, indeterminate, smooth-walled. Conidia hyaline, mostly tetra-radiate, rarely quinque-radiate, guttulate; main axis 11–30 × 2–3 µm ( = 18 × 2.3 µm; n = 30), clavate to obconic with a narrow truncate base, aseptate or 1-septate, cells unequal, straight or curved, bearing a tubular, unbranched, attenuated appendage; arms 47–74 × 1–3 µm ( = 61 × 1.8 µm; n = 30), three, rarely four, delimited from the main axis by septa, straight or curved, each arm 3–5-septate, without constrictions at the septa, arms unequal.
