Pseudocryphonectria elaeocarpicola

Ciri dan struktur

Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, aggregated or solitary, immersed under the host bark, subglobose to pulvinate, yellow to orange, 500–1200 μm wide, 150–450 μm high, multilocular, single ostiolate, forming long orange tendrils. Conidiophores cylindrical, aseptate, hyaline, sometimes reduced to conidiogenous cells. Conidiogenous cells lining inner cavity of conidiomata, phialidic, ampulliform, with attenuated or truncate apices, hyaline, smooth, 12.8–25.7 × 1.7–3.2 μm (n = 50). Conidia dimorphic. Microconidia minute, aseptate, hyaline, smooth, cylindrical, straight, (3.1–)3.3–4(–4.4) × (1.5–)1.6–2(–2.1) μm (n = 50), L/W = 1.6–2.7. Macroconidia aseptate, hyaline, smooth, obclavate, straight or slightly curved, (4.6–)5.1–6.1(–6.6) × (1.4–)1.6–2(–2.2) μm (n = 50), L/W = 2.5–3.9.

Habitat dan peran ekologis

Colonies on PDA flat, spreading, with aerial mycelium and entire margin, white to mouse grey, forming abundant orange conidiomata with orange conidial masses. Pseudocryphonectria elaeocarpicola is the sole species within the new genus, which causes serious stem blight of Elaeocarpus trees. Another notorious pathogen in Cryphonectriaceae, Cryphonectria parasitica, causes serious chestnut worldwide. Morphologically, P. elaeocarpicola is similar to C. parasitica in the appearance of conidiomata with orange conidial tendrils formed on the host bark. However, P. elaeocarpicola can be distinguished from C. parasitica by its obvious dimorphic conidia (Jiang et al. 2019a). Phylogenetically, isolates of P. elaeocarpicola clustered into a distinct clade in the phylograms of Cryphonectriaceae (Figs 2, 3).
