Elongaticollum hedychii

Ciri dan struktur

Saprobic on dead leaves of Hedychium coronarium J. Koenig. Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata 120–140 µm high, 60–70 µm diam., pycnidial, solitary, scattered, superficial, visible as small black spots on host surface, dark brown to black, obpyriform, papillate. Neck up to 80–100 μm long, 20–30 µm diam., elongated, dark brown, usually straight, but sometimes slightly curved. Conidiomatal wall 10–20 µm wide, composed of 4–5 layers of light brown, thick-walled cells, arranged in textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 3–4 × 3–3.5 μm (x̄ = 3.6 × 3.2 μm, n = 10), arising from the inner cell wall of the apex, hyaline, aseptate, smooth, ampulliform. Conidia 4–5 × 1.8–2.2 μm (x̄ = 4.6 × 2.1 μm, n = 30), oval to oblong, smooth, thin-walled, hyaline, aseptate, with 1–2-minute guttules. Colonies on PDA reaching 30 mm diameter after 3 weeks at 20–25 °C, colonies medium sparse, circular, raised, surface slightly rough with entire edge, margin entire, colony from above: light brown to grey at the margin, dark brown at middle, dark brown to black at the center; reverse, light brown to yellowish at the margin, brown at middle, dark brown to black at the center; mycelium light brown to grey with tufts; not producing pigments in PDA.
