Strands of grouped hyphae sometimes arranged in small coils, with conidiogenous cells held on the outside of these coils.

Conidiogenous cells 9.5–17  2–3 µm, hyaline, Type I and Type II (sensu Mostert et al. 2006), subcylindrical to elongate-ampulliform, often slightly swollen at base, not constricted; conidiogenous locus with non-flaring collarette about 1–1.5 µm long and wide. Conidia 4.0–5.5  1.5–2 (–2.5) µm, oblong-elliptic, straight or irregularly curved, ends broadly rounded, 0–septate, hyaline. Conidia on agar surface 6.5–9 (–12)  1.5–2.5 µm, cylindric, curved, allantoid, 0–septate, hyaline. Cultural characteristics: Colonies on MEA 30–32 mm diam. after 16 days, aerial mycelium cottony, uniform in height, pale greyish-green (28B2), with scattered, irregular pinkish patches, margin entire. PDA 18–19 mm diam. after 16 days, aerial mycelium cottony, sparse towards margin, greyish-red (7B2), white to margin, agar surface undulate with radiate ridges, margin entire. OA 20–21 mm diam. after 16 days, aerial mycelium cottony, in ropey upright strands, pale bluish grey (20C2) with irregular greyish red patches, yellow in reverse, yellow pigment diffusing across agar, margin slightly and irregularly scalloped.

In mycelio aerio hyphae singulae vel ad 5 fasciculatae, plerumque hyalinae, laeves. Conidiophora nulla. Phialides 9.5–17  2–3 µm, terminales vel laterales, praecipue typi I vel typi II, cylindricae vel elongato-ampulliformes. Conidia 6.5–9 (–12)  1.5–2.5 µm, oblongo-ellipsoidea, hyalinae, 0–septatae; in agaro 6.5–9 (–12)  1.5–2.5 µm, plerumque allantoidea.

Hyphae smooth or rarely with warts, hyaline to brown, brown hyphae often with verrucose walls, hyphae sometimes aggregated into strands up to about 10 hyphae wide. Conidiophores irregularly and often copiously branched, comprising cells 2–5 µm long. Conidiogenous cells (6.5–)8–12  2–3 µm, pale brown to hyaline, mostly Type II (sensu Mostert et al. 2006), variable in shape, some ampulliform to subulate, slightly constricted at base, others with swollen, almost globose base, and in this case the adjacent cells of the conidiophore similarly swollen and constricted at septa; conidiogenous locus with non-flaring collarette about 1–1.5 µm long and wide, often with lateral conidiogenous locus on a short, narrow branch below septa on conidiophore. Conidia 4.5–6.5  1.5–2 µm, oblong-elliptic, straight to slightly curved, ends rounded, 0–septate, hyaline. Conidia on agar surface 5–7.5  1.5–2.5 µm, often curved, allantoid, cells within conidiophores and conidiogenous cells longer than in aerial mycelium, 12–20 µm long, mixture of Type II and Type III phialides. Cultural characteristics: Colonies on MEA 28–34 mm diam. after 16 days, aerial mycelium almost lacking, colony surface flat, dark brown (9F7) in patches towards the centre, margin entire, yellow pigmentation diffusing from edge of colony across plate. PDA 20–25 mm diam. after 16 days, aerial mycelium sparse, arranged in small upright tufts, agar surface undulate with radiate ridges, in reverse greyish-yellow (4B5), darker and more orange towards margin (5C8), bright yellow pigment diffusing across plate, margin scalloped. OA 23–33 mm diam., aerial mycelium cottony, in ropey upright strands, grey with a hint of yellow (2C2), yellow in reverse, margin scalloped.

In mycelio aerio hyphae singulae vel ad 10 fasciculatae, brunneae vel hyalinae, laeves vel verrucosae. Conidiophora plerumque ramosa. Phialides (6.5–)8–12  2–3 µm, terminales vel laterales, praecipue typi II, ampulliformes vel subuliformes, interdum fundo tumido. Conidia 4.5–6.5  1.5–2 µm, oblongo-ellipsoidea, hyalinae, 0–septatae; in agaro 5–7.5  1.5–2.5 µm, plerumque allantoidea.

Hyphae mostly smooth, rarely with warts, sometimes aggregated into strands of 10–15 hyphae, walls mostly hyaline, sometimes pale brown when aggregated. Conidiophores sparingly branched or lacking, comprising cells 10–15 µm long.
