Description:Mycelium abundantly formed, hyphae narrowly cylindrical-oblong or irregular in outline due to swellings, lateral outgrowth and constrictions, loosely branched, (1–)1.5–5 µm wide, septate, not constricted at septa, subhyaline, pale brown or pale olivaceous brown, almost smooth, asperulate to irregularly verruculose or even verrucose, walls unthickened, occasionally anastomosing. Conidiophores macronematous, solitary, formed laterally or terminally from hyphae, straight or often somewhat flexuous, cylindrical-oblong or irregular in outline due to swellings and constrictions, often subnodulose or with unilateral swellings both terminally and intercalary, sometimes once slightly to distinctly geniculate-sinuous, rarely once branched, 17–190(–210) × (3–)4–5 µm, swellings 5–6.5(–8 ) µm diam, 0–4-septate, not constricted at septa, pale to medium olivaceous brown, smooth or almost so, walls slightly thickened; sometimes a few micro- and semimacronematous conidiophores formed. Conidiogenous cells integrated, mostly terminal, occasionally also intercalary, often quite long, 20–78 µm, cylindrical, subnodulose, with a single or rarely two unilateral swellings and occasionally an additional swollen shoulder at a lower level with 1–3(–4) conspicuous loci restricted to these swellings or shoulders, sometimes once geniculate-sinuous, with up to five loci per cell, loci protuberant, 1.5–2 µm diam, thickened and darkened-refractive. Ramoconidia absent. Conidia solitary or formed in short, unbranched or branched chains, chains with only up to five conidia, solitary, terminal and intercalary conidia ellipsoid, broadly ovoid or subcylindrical, (8–)9.5–17(–19) × (4.5–)5–6.5(–7) µm (av. ± SD: 12.5 ± 2.8 × 5.7 ± 0.9), 0(–1)-septate, hila 1–2 µm diam, basaly formed conidia ellipsoid or subcylindrical, 13–24 × (5–)6–7(–(8) µm (av. ± SD: 18.0 ± 3.1 × 6.4 ± 0.7), 0–1-septate, septum median or in the upper half, becoming curved or sinuous with age, occasionally slightly constricted, pale olivaceous to medium olivaceous brown, verruculose to distinctly verrucose, verrucae up to 1 µm long, dense, walls unthickened or slightly thick-walled, slightly or distinctly attenuated towards apex and base, with 1–2(–3) distal hila, hila 1–2 µm diam, thickened and darkened-refractive. Microcyclic conidiogenesis giving rise to secondary conidiophores occasionally occurring.
