Ciri dan struktur
Saprobic on the rotting inflorescence of Caryota mitis. Sexual morph: Not observed. Asexual morph: Hyphomycetous, helicosporous. Colonies on the substratum superficial, effuse, gregarious, pale brown. Mycelium composed of partly immersed, partly superficial, hyaline to brown, septate, branched hyphae. Conidiophores 150–270 µm long, 4–7.5 µm wide (x̄ = 225 × 5.9 μm, n = 20), macronematous, mononematous, cylindrical, erect, straight to slightly bent, pale brown to deep brown from top towards the base, apex hyaline, septate, mostly unbranched, smooth-walled. Conidiogenous cells 7–15 μm long, 4–7 μm wide (x̄ = 12 × 5.9 μm, n = 20), mono- to polyblastic, cylindrical, integrated, intercalary, brown, smooth-walled; with denticles, 3–6 μm long, 1.5–3 μm wide (x̄ = 4.6 × 2.5 μm, n = 20), arising from the lower portion of conidiophores as tooth-like protrusions, mono- to polyblastic, pale brown to brown, smooth-walled. Conidia 21–47 μm diam. (x̄ = 36.2 μm, n = 40) and conidial filament 2–5 μm wide (x̄ = 3.8 μm, n = 40), 145–345 μm long (x̄ = 257.7 μm, n = 40), solitary, pleurogenous, tightly coiled 3–4½ times, guttulate, become loose in water, hyaline to pale brown, 25–35-septate, smooth-walled. Conidia germinating on water agar and germ tubes produced from conidia within 12 h. Colonies growing on PDA attaining 3 cm diam. after six weeks at 25 °C, irregular, undulate, rough, superficial and partially immersed, brown aerial mycelium mixed with pale brown; reverse brown with pale brown.
