Aureobasidium tremulum

Ciri dan struktur

After 14 days of incubation at 25 °C in the dark, colonies on PDA reaching 27–30 mm diam., surface flat, spreading with irregular, lobate margin, orange white (5A2), light gray (5B2) at the margin; on MEA reaching 24–35 mm diam., surface flat, spreading with irregular margin, velvety, purplish gray (14D2) in outer ring, brownish gray (4E2) towards to the center; on OA 30–50 mm diam., surface flat, spreading with irregular margin, velvety, aerial mycelium sparse, floccose, light gray (4B1) in outer ring, grayish brown (5E3) towards to the center, yellowish brown (5E8) at center. Anamorph in vitro dematiaceous hyphomycetes. Vegetative hyphae (2.4–)4.0–5.8(–7.6) μm wide, mostly hyaline, branched, septate, smooth-, thin-walled, getting darker and thicker, constricted at the septa, minutely echinulate with age, anastomosis observed. Conidiogenous cells (8.5–)9.5–17.5(–20.6) × (3.7–)5.2–7.0(–8.5) μm (x̄ = 13.9 × 6.1 μm, n = 25), undifferentiated, intercalary, rarely terminal, or producing conidia percurrently from short lateral denticles, giving rise to conidia that aggregate in a mucoid mass, or differentiated from hyphae. Conidia (4.6–)6.8–10.0(–17.3) × (2.8–)3.9–5.5(–7.2) μm (x̄ = 8.1 × 4.5 μm, n = 170), fusoid, obovoid to ellipsoid, or oval, or globose, hyaline, becoming light brown to brown with age, aseptate, occasionally with an indistinct truncated base and a hilum, minutely echinulate, budding occasionally observed. Chlamydospores (7.0–)8.5–13.0(–16) μm wide (x̄ = 10.6 μm, n = 30), frequent produced in aerial hyphae, mostly intercalary, solitary or in branched chains, sub globose to ellipsoidal, pigmented, light to dark brown, smooth-, thick-walled, septate, constricted near the septa.
