Diaporthe heliconiae

Ciri dan struktur

Diaporthe heliconiae can be distinguished from the phylogenetically closely related species D. subclavata F. Huang, K.D. Hyde & Hong Y. Li in smaller α-conidia. Asexual morph: Conidiomata pycnidial, solitary or aggregated in groups, erumpent, thin-walled, superficial to embedded on PDA, dark brown to black, globose or subglobose, exuding creamy yellowish spiral conidial cirrus from the ostioles. Conidiophores hyaline, aseptate, cylindrical, straight to sinuous, branched, 16.5–25.0 × 1.3–1.8 µm. Alpha conidiogenous cells, cylindric-clavate, terminal, few guttulate, 11.5–18.0 × 1.0–1.5 µm. Beta conidiogenous cells, prismatic, terminal, few guttulate, 10.0–14.1 × 1.0–1.2 µm. Alpha conidia, hyaline, smooth, aseptate, ellipsoidal, 2–4 guttulate, apex subobtuse, base subtruncate, 5.0–6.5 × 2.0–2.5 µm (mean = 6.1 × 2.3 μm, n = 20). Beta conidia hyaline, aseptate, filiform, slightly curved, tapering towards the apex, 25.0–33.5 × 1.0–1.5 µm (mean = 29.4 × 1.3 μm, n = 20). Gamma conidia and sexual morph not observed. Pure culture was isolated by subbing hyphal tips growing from surface sterilized infected plant material. Colonies on PDA cover the Petri dish diameter after incubation for 15 days in dark conditions at 25 °C. Aerial mycelium abundant, cottony, white, dense in the center, sparse near the margin. White on surface side, white to tanned on reverse side.
