Conidiophores 101−115 × 5.2−8.1 µm (x̄ = 110.9 × 6.3 µm, n = 20), solitary or aggregated in dense fascicles, or synnematous conidiomata, arising from internal hyphae, sometimes from superficial hyphae pale olivaceous or brown, unbranched or branched, aseptate or pluriseptate, smooth, sometimes slightly verruculose, straight or curved. Conidiogenous loci conspicuous, somewhat thickened and darkened-refractive, usually planate. Conidia 28−50 × 5.2−9 µm (x̄ = 42.2 × 6.1 µm, n = 20), solitary or sometimes catenate, pale olivaceous to pale brown, amero- to scolecosporous, aseptate to pluriseptate, euseptate or sometimes with a few distosepta, smooth or finely verruculose; hilum slightly thickened and darkened.
