Conidiophores unbranched, erect, straight or more usually irregularly bent, 3–10 speptate, 22–84 µm × 6–7 µm, brown but paler above and tapering more or less abruptly to about 2 um which is the width of the separating cell. They have been arising on the host as lateral branches of hyphae and they are generally scattered. Conidia dry, cylindrical with rounded ends with a slightly raised basal scar 2 µm wide; 62–115 µm × 8–10 µm, hyaline to pale brown and then paler at the apex of the base, 15-septate at maturity, apical cell may or may not bear a hyaline, septate, filiform, straight or slightly curved appendage, 32–126 µm × 1.5–2.0 µm.
