Dendrostoma aurorae

Ciri dan struktur

Dendrostoma aurorae differs from D. chinensis and D. shandongense by the existence of obvious central column. Sexual morph not observed. Asexual morph: Conidiomata pycnidial, conical to pulvinate, occurring separately, bright yellow to orange, semi-immersed in bark, 300–500 μm high, 800–1400 μm diam.; wall of several layers of bright yellow textura angularis; conidiomata exuding slimy orange masses of conidia; central column beneath the disc more or less conical, pale yellow. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner walls of the cavity, hyaline, smooth, subcylindrical to ampulliform, 4–15 × 2.5–4 μm. Conidia hyaline, aseptate, smooth, multiguttulate, thin-walled, ellipsoid to fusoid, straight to curved, (7.2–)8.1–9.8(–10.3) × (2.1–)2.3–2.6(–2.8) μm, l/w = (2.7–)3.2–4.1(–4.2) (n = 50).

Habitat dan peran ekologis

On PDA, cultures are initially white, becoming isabelline after 2 weeks. The colonies are flat with irregular edge; texture uniform within 1 month at 25 °C in the dark. Dendrostoma aurorae was discovered on stems of dying chestnut trees and appears morphologically similar to the chestnut blight pathogen, Cryphonectria parasitica. However, these two diaporthalean pathogens can be distinguished by the existence of a central column inside the conidiomata of Dendrostoma aurorae. In the genus Dendrostoma, D. aurorae differs from D. chinensis and D. shandongense by the existence of an obvious central column.
