Cytospora euonymina

Ciri dan struktur

Sexual morph: not observed. Asexual morph: Conidiomata pycnidial, immersed in the bark, scattered, producing black area on bark, erumpent through the surface, with multiple locules. Conceptacle absent. Ectostromatic disc honey to dark mouse grey, conspicuous, circular to ovoid, 200–500µm in diam, with one ostiole per disc. Ostiole in the centre of the disc, black, conspicuous, 80–200 μm diam. Locules numerous, subdivided frequently by invaginations with common walls, 400–750 µm in diam. Conidiophores borne along the locules, hyaline, unbranched or occasionally branched at the base or in the middle, thin-walled, 8–12 × 1.5–2 (av. = 10 ± 2.1 × 1.8 ± 0.3, n = 50) μm, embedded in a gelatinous layer. Conidiogenous cells enteroblastic, phialidic. Conidia hyaline, elongate-allantoid, smooth, aseptate, 5–7 × 1–2 (av. = 6 ± 0.5 × 1.5 ± 0.3, n = 50) µm. Cultures on PDA are initially white, irregular, lacking aerial mycelium, fast growing up to 5 cm diam. after 3 d. Colonies pale white to light salmon after 30 d, pycnidia distributed sparsely over the medium surface.

Colonies pale white to light salmon after 30 d, pycnidia distributed sparsely over the medium surface. Cytospora euonymina was isolated from Euonymus kiautschovicus in Shanxi Province, China (Fan et al. 2020). It is characterised by having pycnidia covered by the darkened cuticle.
