Conidia produced in colourless wet heads mostly <40 μm, sometimes to 70(–100) μm diam, eventually conidia lying on the agar surface. Phialides (8–)10–17(–26) × (1.8–)2.3–3.0(–4.0) μm, l/w (2.8–)3.5–6.5(–10.3), (1.2–)1.7–2.3(–3.0) μm wide at the base (n = 94), lageniform, long, slender, often thickened below the middle, less commonly in the middle, typically constricted below a
long neck, straight or slightly curved upwards. Conidia (3.0–)3.5–5.0(–7.0) × (2.0–)2.2–2.7(–3.0) μm, l/w (1.2–)1.5–2.1(–2.5) (n = 90), hyaline, oblong, less commonly ellipsoidal, often slightly constricted in the middle, smooth, finely multiguttulate or with 1–2 larger guttules; scar indistinct. MLN4924 mw conidiation also occurring within the agar, particularly Savolitinib in proximal and
central AZD8931 areas, conidia formed in heads <15 μm with maximal 15 conidia per head. At 15°C minute sinuous secondary hyphae dominant, particularly at the colony margin. Conidiation colourless, effuse, spreading across the entire colony. At 30°C colony denser in the centre; hyphae thin; conidiation effuse, less abundant than at lower temperatures. On PDA after 72 h 6–10 mm at 15°C, 20–24 mm at 25°C, 7–15 mm at 30°C; mycelium covering the plate after 9–10 days at 25°C. Colony dense, of few flat, broad, concentric zones with irregular outline and a whitish to pale yellowish, downy, hairy, finely floccose or farinose surface. Aerial hyphae numerous, loose, only few mm high, without a distinct Protein Tyrosine Kinase inhibitor orientation, becoming fertile. Autolytic activity inconspicuous or moderate, no coilings seen. Reverse yellowish, cream, 3A3, 4AB3–4. Odour indistinct or slightly sour. Conidiation noted after 2 days at 25°C, effuse, spreading from the centre across the entire colony, abundant, dense in downy areas, short and ascending on aerial
hyphae. Conidiophores loose, verticillium-like; phialides in whorls of 3–5; conidia hyaline, formed in wet heads to 50(–70) μm diam. At 15°C colony dense, hyphae thin, yellowish 3A3, surface downy to farinose, not zonate or 2 irregular zones; conidiation effuse. At 30°C colony compact, circular, dense, finely zonate, glabrous or centre hairy to fluffy. Autolytic excretions lacking at the colony margin, frequent inside the colony, yellow-brown. Reverse yellowish, 4AB3–4. Odour yeast-like to sour. Conidiation effuse, scant or in dense lawns. On SNA after 72 h 9–12 mm at 15°C, 27–32 mm at 25°C, 3–11 mm at 30°C; mycelium covering the plate after 6–7 days at 25°C. Colony similar to CMD, but denser and surface hyphae degenerating, appearing empty. Mycelium not zonate, colony becoming zonate by conidiation. Autolytic activity moderate to conspicuous, coilings nearly lacking. No diffusing pigment, no distinct odour produced. Chlamydospores noted after 2–3 weeks, scant, mainly in the centre; appearing after 10 days and more frequent at 30°C, (4–)5–8(–12) × (4.0–)4.5–6.0(–7.0) μm, l/w 1.0–1.5(–2.
