Description:Mycelium consisting of smooth, branched, septate, 4–5 μm diam, brown hyphae. Conidiophores reduced to conidiogenous loci on hyphae, inconspicuous, 1–5 × 2 μm, not thickened nor darkened. Conidia solitary, medium brown, smooth, guttulate, star-shaped, with two globose central cells giving rise to four irregular radiating arms of 4–5(–7) cells, tapering from point of attachment to subobtuse apices, constricted at septa, 30 – 80 × 8 –10 μm; conidia also have a fifth branch of 1– 2 cells tapering to a subobtuse apex, 15 – 30 × 7– 8 μm, which is the branch that attaches to the conidiogenous locus on hyphae. Microconidiogenous cells on hyphae solitary, ampulliform, medium brown, smooth, phialidic, 10–17 × 3–4 μm. Microconidia bacilliform, hyaline, smooth, aseptate, ends rounded, 2–3 × 2 μm.

Culture characteristics — Colonies erumpent, spreading, with moderate aerial mycelium and even, lobate margins, reaching 10–20 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface olivaceous grey, reverse iron-grey.
