Description:Mycelium immersed and superficial, dimorphic, sparingly branched, 2-5 µm wide, septate, not constricted at septa, hyaline to subhyaline or olivaceous-brown, sterile hyphae smooth, fertile hyphae giving rise to conidiophores irregularly rough-walled, Zasmidium(Stenella)-like, often irregular in outline, walls unthickened to somewhat thickened. Conidiophores macronematous, sometimes also micronematous, arising laterally or terminally from plagiotropous or ascending hyphae, solitary, sometimes in loose groups of two or three, erect, straight to slightly flexuous, cylindrical-oblong, unbranched or once, sometimes twice branched, lateral branches as short outgrowth just below a septum or relatively long, in an angle of 45-90°, 28-90(-145) — 3-4 µm, pluriseptate, not constricted at septa, pale olivaceous to olivaceous-brown, paler towards apices, smooth to somewhat irregularly rough-walled, similar as hyphae, walls thickened, up to 1 µm wide; micronematous conidiophores shorter, narrower and paler, 14-65 — 2-3 µm, septate. Conidiogenous cells integrated, terminal and intercalary, cylindrical-oblong, 5-35 µm long, with 1-5 protuberant, denticle-like loci, often aggregated or sitting on small lateral prolongations, broadly truncate, 1.2-2 µm diam, thickened and distinctly darkened, secondary ramoconidia sitting like a whirl at the tip of conidiophores. Ramoconidia occasionally formed, with a broadly truncate base, not darkened but slightly refractive. Conidia catenate, in branched chains, numerous, often dichotomously branched, especially in the terminal part, small terminal conidia ovoid to obovoid, sometimes subglobose or globose, 3-5 — 2-3 µm (av. ± SD: 4.3 ± 0.8 — 2.6 ± 0.4), aseptate, rounded at the apex, attenuated towards the base, smooth, thin-walled, intercalary conidia ovoid-ellipsoid, 5-8(-12) — 3-4 µm (av. ± SD: 7.6 ± 1.7 — 3.6 ± 0.4), aseptate, distinctly attenuated towards the base, with 1-3 distal hila, sometimes situated on short lateral prolongations at the distal end, secondary ramoconidia ellipsoid to fusiform or subcylindrical, with (1-)2-3(-4) distal hila, 7-18(-23) — (2.5-)3-5(-6) µm (av. ± SD: 12.8 ± 3.9 — 3.9 ± 0.7), 0-1(-2)-septate, not constricted at septa, only very slightly attenuated towards apex and base, base broadly truncate, pale brown or pale olivaceous-brown, smooth, walls unthickened or almost so, hila protuberant, denticulate, 0.5?2 µm diam, thickened, distinctly darkened-refractive; microcyclic conidiogenesis not observed.

Culture characteristics: Colonies on PDA attaining 8-18 mm diam after 1 mo, pale olivaceous-grey to olivaceous-grey, sometimes olivaceous due to abundant sporulation, reverse olivaceous-grey, velvety to fluffy, margin feathery to glabrous, regular, slow growing, aerial mycelium loose to dense, more abundant at few areas, fluffy, few prominent exudates formed, sporulation profuse. Colonies on MEA reaching 8-18 mm diam after 1 mo, grey-olivaceous to olivaceous-grey, whitish to smoke-grey due to aerial mycelium, reverse olivaceous-grey to iron-grey, velvety to woolly, margin very narrow, white feathery, aerial mycelium dense, high, covering some parts of the colony, abundant, without conspicuous exudates, sporulation profuse.
