Aerial hyphae variable, scant or frequent, short or long, distinctly less than on PDA and SNA, becoming fertile, collapsing to form inconspicuous whitish floccules. Autolytic activity and coilings absent or scant. Odour slightly unpleasant, reminiscent of Sarcodon imbricatus mixed with apple. Chlamydospores noted after 9–11 days, terminal and intercalary, mainly in surface

hyphae, (7–)8–13(–19) × (5–)6–10(–12) μm (n = 30), l/w 1.0–1.7(–2.7) (n = 30), subglobose, clavate or ellipsoidal, smooth, often with a pedicel. Conidiation noted after 1–2 days, effuse, colourless, Evofosfamide acremonium- to verticillium-like, spreading from the plug on surface and aerial hyphae. Conidia produced in minute wet heads <40 μm diam on long thin phialides in steep whorls of 4–6. At 30°C growth soon stopping, hyphae forming pegs;

yellow pigment diffusing into the agar; conidiation scant. On PDA after Blasticidin S 72 h 2–4 mm at 15°C, 3–5 mm at 25°C, Bindarit <1 mm at 30°C; mycelium covering the plate after ca 2 weeks at 25°C. Colony circular, dense to opaque, indistinctly zonate; of richly branched, narrow, radial hyphae. Aerial hyphae abundant, dichotomously branched, first forming a white flat mat in distal areas, turning yellowish and ascending as a loose or dense fluffy mat, becoming fertile up to the lid of the Petri dish. Autolytic excretions scant; no coilings noted. Colony surface turning reddish-brown, 8CD5–6, hyphal mat whitish to yellow 4A3–4 or pale orange. Reverse orange-brown, 5–6CD7–8, to dark brown, 6F7–8, 7EF7–8, in the centre, yellow, (-)-p-Bromotetramisole Oxalate 4AB4–5, orange, 4A5–7, to orange-brown, 6–7CD7–8, in the residual colony. Odour as on CMD or more fruity. Conidiation noted after 2 days, effuse, spreading from the

centre on surface and aerial hyphae, acremonium- to irregularly verticillium-like. Conidiophores arising from aerial hyphae mostly in steep angles, mostly unpaired, short, unbranched or once loosely rebranching with side branches similar to the main axis, mostly 1–2 celled. Conidiophores and aerial hyphae 4–7 μm wide, attenuated upwards and terminally 2–3 μm wide. Phialides divergent in whorls of 2–4 on the apices of main and side branches, and solitary or paired along their length. Phialides (10–)16–28(–38) × (1.8–)2.0–3.0(–3.5) μm, l/w (3–)7–11(–13), (1.5–)1.7–2.5(–3.5) μm wide at the base (n = 30), subulate, equilateral, only rarely thickened close to the base. Conidia formed in low numbers in minute wet heads to 30 μm diam; conidia (3.2–)3.5–5.0(–6.0) × (2.0–)2.3–2.6(–2.8) μm, l/w (1.2–)1.4–2(–2.5) (n = 30), hyaline, ellipsoidal to oblong, smooth, with few small guttules, and often with a projecting scar. At 15°C colony similar to that at 25°C, but more regularly zonate, aerial hyphae forming a flatter mat. At 30°C hardly growing, yellow pigment forming minute radiating hair-like crystals around the plug.
