Dendrostoma parasiticum

Ciri dan struktur

Dendrostoma parasiticum is distinguished from D. quercus by its shorter and narrower conidia. Sexual morph not observed. Asexual morph: Conidiomata pycnidial, conical to spherical, occurring separately, yellow, semi-immersed in bark, 350–600 μm high, 1000–1800 μm diam.; wall of several layers of bright yellow textura angularis; central column beneath the disc conical, bright yellow. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner walls of the cavity, hyaline, smooth, subcylindrical to ampulliform, 7–12 × 2–3.5 μm. Conidia hyaline, aseptate, smooth, multiguttulate, thin-walled, fusoid, straight, (9.2–)9.3–11.7(–13.6) × (2.7–)2.8–3.3(–3.6) μm, l/w = (2.7–)3–3.9(–4.2) (n = 50).

Habitat dan peran ekologis

Dendrostoma parasiticum is distinguished from D. quercus by its shorter and narrower conidia. On PDA, cultures are initially white, becoming dark orange after 2 weeks. The colonies are flat with irregular edge; texture uniform, producing concentric circles within 1 month at 25 °C in the dark. Dendrostoma parasiticum constitutes a widely distributed species occurring on several Fagaceae tree species including Castanea mollissima, Quercus aliena, Q. aliena var. acuteserrata and Q. wutaishansea. Dendrostoma parasiticum appears to be associated with tree dieback, canker and even tree death, although its pathogenicity remains unproven. Dendrostoma parasiticum is close to D. quercus in the phylogram (Fig. 2), but differs from D. quercus with shorter (9.3–11.7 μm in D. parasiticum vs. 13.3–16.1 μm in D. quercus) and narrower (2.8–3.3 μm in D. parasiticum vs. 3.5–4.2 μm in D. quercus) conidia.
