Rhizoids abundant, emerging ventrally or latero-ventrally, monohyphal, 4.8-6.8 μm in diam., with disk-like ending. Hyphal bodies hyphae-like, or irregularly rounded. Conidiophores branched.

Secondary conidia resembling primary conidia, 20.6-29.4 × 7.9-11.1 μm, L/D=2.76-3.36, or capilliconidia. Capilliconidia 20.6-31.7 × 7.9-11.1 μm, L/D=2.46-2.96, elongate falciform, sometimes papillate at one or both ends. Capillary slender, 96.8-108.7 × 2.4-3.2 μm. Resting spores not observed.
