Colony hyaline, thin, not or indistinctly zonate, with wavy margi

Colony hyaline, thin, not or indistinctly zonate, with wavy margin; mycelium loose, hyphae thin, little branched, irregularly oriented and coarsely wavy, causing radially oriented fan-shaped GSK1838705A concentration structures. Surface becoming downy, floccose or farinose along the margin

due to conidial heads. Aerial hyphae scant, short. Autolytic activity moderate, excretions small, hyaline to yellowish; coilings rare or absent: No diffusing pigment formed. Odour fruity. Chlamydospores uncommon, only seen at 30°C, intercalary, rarely terminal, (11–)13–26(–35) × (8–)9–20(–27) μm, l/w (1–)1–1.7(–2.1) μm (n = 30), broadly ellipsoidal, subglobose, pyriform or oblong. Conidiation starting after 2 days on short, simple or scarcely asymmetrically branched, acremonium-like conidiophores, loosely disposed, becoming dense along the margin of the plate; with solitary subulate phialides and wet conidial heads to 150 μm diam. Conidia as described on SNA, hyaline, conspicuously swelling after transfer to fresh agar. Some conidiation also submerged in the agar. Fruity, apple-like odour noted also at 15 and 30°C. At 15°C fan-shaped colony

becoming diffuse yellow, 2–3AB3–4, conidiation dense along the margin. At 30°C colony irregular, fan-shaped to lobed; conidiation concentrated in powdery or granular distal concentric zones, in white tufts to 1.5 mm diam or in broad white spots. Tufts loosely selleck chemicals llc asymmetrically branched, right angles frequent. On PDA after 72 h 10–11 mm at 15°C, 30–33 mm at 25°C, 20–22 mm at 30°C; mycelium covering the plate after 5–6 days at 25°C. Colony flat, indistinctly zonate, imbricate, mottled due to varying mycelial density, white in denser regions; margin wavy to lobed, thinner than the Cyclosporin A molecular weight residual colony. Mycelium dense; surface hyphae thick. Surface Farnesyltransferase becoming farinose or granulose due to conidial heads. Aerial

hyphae in lawns of varying density, short, thick, erect, often fasciculate, becoming fertile. Sometimes dense white spots appearing, with brownish droplets, turning golden brown. Autolytic excretions abundant, small, <50 μm diam; coilings absent. Agar/reverse turning pale rosy with yellow tones or dull orange around the plug, 5AB4–5. Odour fruity, apple-like. No chlamydospores seen. Conidiation noted after 2 days, effuse, in a dense lawn of simple, short, scarcely branched, acremonium-like conidiophores 3–5 μm wide terminally, 6–8 μm basally, with 1–2 terminal phialides, spreading from the centre. Conidia formed in numerous wet heads 20–80(–160) μm diam, confluent, becoming irregular. Phialides (6–)25–53(–76) × (2.8–)3.5–5.5(–7.0) μm, l/w (2–)6–12(–18), (2.5–)3.5–5.0(–6.5) μm (n = 90) wide at the base, subulate or cylindrical, straight, curved or sinuous. Conidia (5–)7–14(–18) × (3–)4–8(–12) μm, l/w (1.1–)1.3–2.0(–2.7) (n = 90), hyaline, quite variable, subglobose, oval, pyriform, oblong to cylindrical, smooth, with minute guttules and indistinct or truncate scar.
