Aureobasidium melanogenum

Ciri dan struktur

After 14 days of incubation at 25 °C in the dark, colonies on PDA reaching 45–65 mm diam., surface flat, spreading with entire margin, zonate, orange white (5A2), with brownish gray (4E2) to olive brown (4E6) at the margin; on MEA reaching 65–70 mm diam., surface flat, spreading with entire margin, velvety, zonate, dark brown (6F8) at center, becoming brownish orange (6C8), with brownish gray (4E2) and white at the margin; on OA 60–75 mm diam., surface flat, spreading with irregular margin, velvety, grayish orange (6B5), with brownish gray (4E2) at the margin. Anamorph in vitro dematiaceous hyphomycetes. Vegetative hyphae (2.3–)3.0–5.5(–8.0) μm wide, mostly hyaline, light brown to brown, branched, septate, constricted at the septa, smooth, thin-walled, getting darker and thicker with age. Conidiogenous cells (3.8–)5.3–11.0(–12.5) × (3.2–)4.0–7.5(–8.3) μm (x̄ = 8.7 × 5.3 μm, n = 25), undifferentiated, intercalary, rarely terminal, producing conidia percurrently from indistinct lateral denticles, giving rise to conidia that aggregate in a mucoid mass, or differentiated from hyphae, hyaline to lightly melanized. Conidia (3.6–)5.5–8.5(–11.4) × (2.0–)2.8–6.0 μm (x̄ = 7.1 × 4.1 μm, n = 150), obovoid to ellipsoid, or subglobose, hyaline, becoming lightly melanized with age, aseptate, occasionally with an indistinct truncated base and a hilum, guttulate, smooth-walled. Chlamydospores (10.0)11.5–14.0(–16.3) μm wide (x̄ = 12.8 μm, n = 50), frequent produced in aerial hyphae, mostly intercalary, solitary or in branched chains, subglobose to ellipsoidal, pigmented, light to dark brown, smooth-, thick-walled, septate, constricted near the septa.

Habitat dan peran ekologis

Flowers of Jasminum sambac and Ocimum tenuiflorum in Thailand (this study). Aureobasidium melanogenum is found worldwide in diverse environments and materials, including air, soil, water, and indoor and plant surfaces, and is also considered an opportunistic human pathogen (Zalar et al. 2008; Gostinčar et al. 2014; Nasr et al. 2018; da Silva et al. 2024; Černoša et al. 2025; Patel et al. 2025).
