Diaporthe chrysalidocarpi

Ciri dan struktur

Diaporthe chrysalidocarpi can be distinguished from the phylogenetically most closely related species D. spinosa by longer beta conidia (28.0–32.5 × 1.2–1.6 vs. 18.5–30.5 × 1.0–1.5 μm), and from other species D. fulvicolor by the types of conidia (D. chrysalidocarpi produces only beta conidia, while D. fulvicolor produces only alpha conidia) and several loci (25/491 in the ITS region, 18/471 TUB, 4/298 TEF, 28/458 CAL and 13/441 HIS). Asexual morph: Leaf spots irregular, pale brown in center, brown to tan at margin. Conidiomata pycnidial, scattered or aggregated, black, erumpent, raising above surface of culture medium, subglobose, exuding white or yellowish creamy conidial droplets from central ostioles after 30 days in light at 25 °C; pycnidial wall consists of black to dark brown, thin-walled cells. Conidiophores 27.5–35.0 × 1.4–2.0 μm, hyaline, slightly branched, swelling at base, subcylindrical, septate, smooth, straight or curved. Conidiogenous cells 10.5–23.0 × 1.4–1.8 μm, phialidic, cylindrical, terminal, straight to sinuous, tapering towards apex. Beta conidia 28.0–32.5 × 1.2–1.6 μm (mean = 30.3 × 1.3 μm, n = 20), filiform, hyaline, straight or slightly curved, aseptate, base subtruncate, tapering towards the base. Alpha conidia and gamma conidia not observed. Sexual morph not observed. Cultures incubated on PDA at 25 °C in darkness, growth rate 13.3–15.2 mm diam/day, initially white, becoming greyish, reverse pale brown, with concentric rings of dense, sparse hyphae, irregular margin, fluffy aerial mycelium at center, pycnidia forming after 15 days.
