Diaporthe camelliae-sinensis

Ciri dan struktur

Diaporthe camelliae-sinensis can be distinguished from the closely related species D. macintoshii R.G. Shivas et al. and D. vangueriae Crous based on ITS, TUB and TEF loci. Diaporthe camelliae-sinensis differs from D. macintoshii in smaller α-conidia and from D. vangueriae in shorter β-conidia. Asexual morph: Conidiomata pycnidial, multi-pycnidia grouped together, globose, black, erumpent, coated with white hyphae, thick-walled, exuding creamy to yellowish conidial droplets from central ostioles. Conidiophores hyaline, smooth, septate, branched, densely aggregated, cylindrical, straight to sinuous, swelling at the base, tapering towards the apex, 10–15 × 1.5–2 μm. Conidiogenous cells 8.5–12 × 2–2.8 μm, phialidic, cylindrical, terminal, slightly tapering towards the apex. Alpha conidia, hyaline, smooth, aseptate, ellipsoidal to fusoid, 2–4 guttulate, apex subobtuse, base subtruncate, 7.5–10 × 1.8–2.5 µm (mean = 8.5 × 2.2 μm, n = 20). Beta conidia hyaline, aseptate, filiform, sigmoid to lunate, mostly curved through 90–180°, tapering towards the apex, base truncate, 20–30 × 1.2–1.6 µm (mean = 25.6 × 1.3 μm, n = 20). Gamma conidia and sexual morph not observed. Pure culture was isolated by subbing hyphal tips growing from surface sterilized diseased material. Colonies on PDA cover the Petri dish diameter after incubation for 15 days in dark conditions at 25 °C, cottony and radially with abundant aerial mycelium, sparse in the margin. With a tanned concentric ring of dense hyphae, white on surface side, white to pale yellow on reverse side.
