Morphological description
Hyphae hyaline, septate, branched, smooth, 1.0–3.0 μm wide. Asexual morph Arthroconidia abundant, intercalary, terminal, or lateral, unicellular, solitary, straight or curved, hyaline, intercalary conidia cylindrical, terminal and lateral conidia cylindrical or ellipsoidal with truncated base, sometimes irregularly swollen, sessile or short stalked, 2.5–5.0 × 2.0–3.0 µm ( x̄ ± SD = 3.7 ± 0.56 × 2.4 ± 0.24 µm, n = 60), frequently separated by 1–3 autolytic connective cells. Sexual morph not observed. Culture characteristics—Colonies on PDA attaining 21–26 mm diam. after 4 weeks, flat, felty, annular, margin undulate, beige (30A2) at margin, white to pale orange (3A2) in center. Reverse annular, beige (30A2) to pale brown (4B6). Colonies on OA attaining 25–28 mm diam. after 4 weeks, flat, pulverulent, margin undulate, white. Reverse floralwhite (1A2). Sporulation within 3 weeks on OA. Colonies on SNA attaining 16–18 mm diam. after 4 weeks, radially striate with rhizoid margin, white. Reverse white.
