Diaporthe betulina

Ciri dan struktur

Diaporthe betulina can be distinguished from the phylogenetically closely related species D. betulae in smaller locule and wider alpha conidia. Conidiomata pycnidial, conical, immersed in bark, scattered, erumpent through the bark surface, with a solitary undivided locule. Ectostromatic disc brown to black, one ostiole per disc, 290–645 μm diam. Ostiole medium black, up to the level of disc. Locule undivided, 670–905 μm diam. Conidiophores 12.5–17.5 × 1.5–2 μm, cylindrical, hyaline, phiailidic, branched, straight or slightly curved. Alpha conidia hyaline, aseptate, ellipsoidal to fusiform, 0–2-guttulate, sometimes acute at both ends, 8–10 × 2.5–3 μm (av. = 9 × 2.6 μm, n = 30). Beta conidia hyaline, aseptate, filiform, straight or hamate, eguttulate, base subtruncate, tapering towards one apex, 26–32.5 × 1 µm (av. = 30 × 1 µm, n = 30).

Habitat dan peran ekologis

Cultures incubated on PDA at 25 °C in darkness. Colony flat with white felty aerial mycelium, turning white to dark brown aerial mycelium, conidiomata irregularly distributed on the agar surface. Diaporthe betulina was isolated from Betula spp. cankers in Heilongjiang Province. Three strains representing D. betulina cluster in a well-supported clade and appear most closely related to D. betulae, which was also isolated from Betula platyphylla in Sichuang Province (Du et al. 2016). Diaporthe betulina can be distinguished based o n ITS, his3, tef1 and tub2 loci from D. betulae (11/461 in ITS, 9/453 in his3, 12/336 in tef1 and 7/695 in tub2). Morphologically, D. betulina differs from D. betulae in smaller locule (470–945 vs. 600–1250 μm) and wider alpha conidia (3–4 vs. 2.5–3 μm) (Du et al. 2016).
