0–2.5 μm at the ends; often with paired branches towards the ends. Phialides borne on cells 2.0–3.5 μm wide, solitary or in whorls of 2–3(–5), divergent, lageniform to beak-like, long, often curved or sinuous, often longer when solitary. Conidia formed in minute wet heads, minute, pyriform, oval or subglobose, less commonly oblong and larger; hyaline, smooth, with few finest guttules; abscission scar often distinct, projecting, short and flat. Measurements united with those determined on CMD. On SNA after
72 h 4–6 mm at 15°C, 4–8 mm at 25°C, < 1 mm selleck chemicals llc at 30°C; mycelium covering plate after 2–3 weeks at 25°C. Colony similar as on CMD, slightly more irregular and mycelium looser; hyaline, margin
diffuse, growth faster inside the agar. Surface becoming floccose, with fine white granules or floccules (0.2–0.6 mm) of larger or aggregated conidiophores. Autolytic activity moderate to strong, coilings abundant. No distinct odour, no pigment, no chlamydospores noted. Conidiation effuse, starting after 3–4 days at 25°C around the plug, spreading across the entire colony, denser in downy areas; similar to but more abundant than on CMD. Phialides often sinuous, spiny, on thick stipes, conidia formed in minute wet heads to 20–30(–60) μm diam, colourless. At 15°C poor growth observed.
