Aureobasidium castaneae

Ciri dan struktur

After 14 days of incubation at 25 °C in the dark, colonies on PDA reaching 34–45 mm diam., surface flat, spreading, round with radiating, irregular margin, velvety, slimy, pale yellow (2A3), becoming olive brown (4E5) at the margin; on MEA reaching 28–35 mm diam., surface flat, spreading, round with radiating, irregular margin, velvety, slimy, dark brown (6F8) at center, becoming olive brown (4E5) to smoke brown (4E2) and white at the margin; on OA 32–45 mm diam., surface flat, spreading with irregular margin, velvety, slimy, pale yellow (2A3), becoming brownish gray (4E2), yellowish brown (5E8) at the margin. Anamorph in vitro dematiaceous hyphomycetes. Vegetative hyphae 2.0–5.0(–6.6) μm wide, mostly hyaline, branched, septate, smooth, thin-walled, becoming light brown to brown, guttulate, thick-walled. Conidiogenous cells (4.8–)6.0–14.0(–16.0) × 2.5–6.0(–6.7) μm (x̄ = 9.7 × 4.6 μm, n = 25), undifferentiated from hyphae, intercalary, rarely terminal, producing conidia percurrently from indistinct lateral denticles, giving rise to conidia that aggregate in a mucoid mass, or differentiated from hyphae, occasionally elongated, solitary, erect to lightly curved, hyaline becoming lightly melanized with age. Conidia (4.3–)5.0–9.0(–11.0) × (2.5–)3.0–4.5(–5.6) μm (x̄ = 7 × 3.7 μm, n = 150), obovoid to ellipsoid, globose to subglobose, hyaline, becoming light brown to brown with age, aseptate, occasionally with an indistinct truncated base and a hilum, guttulate, smooth-walled, budding occasionally observed. Endoconidia (2.9–)3.4–5.6 × 1.6–2.5 μm (x̄ = 4.0 × 1.9 μm, n = 25), obovoid to ellipsoid, hyaline, occasionally seen in intercalary hyphal cells.
