Coryneum songshanense

Ciri dan struktur

Coryneum songshanense can be distinguished from the morphologically similar C. sinense by its narrower conidia. Associated with canker on twigs of Quercus dentata. Sexual morph: Pseudostromata 0.3–1 mm diam., typically distinct, circular, without perithecial bumps, containing up to 6 perithecia embedded in a well-developed entostroma. Ectostromatic disc distinct, circular, black, 0.3–0.5 mm diam. Central column and entostroma grey. Ostioles inconspicuous and often invisible at the surface of the ectostromatic disc. Perithecia (150–)200–450(–550) μm diam. (n = 20), globular, somewhat flattened at the base with black short neck. Asci 75–145 × 17–23 μm, 8-spored, unitunicate, clavate, shortly pedicellate, apically rounded, with an inconspicuous apical ring. Ascospores (24.1–)25.5–35.4(–38.2) × (7.5–)7.9–9.8(–10.6) μm, l/w = (3.0–)3.3–3.8(–4.2) (n = 50), 2-seriate, fusiform, ends pointed, uniseptate or aseptate, not constricted at the septa, hyaline, guttulate, smooth-walled. Asexual morph: Conidiomata acervular, 0.2–0.6 mm wide, 0.2–0.5 mm high, solitary, erumpent through the outer periderm layers of the host, scattered, surface tissues above slightly domed. Conidiophores 15–35 μm long, 4–7 μm wide, unbranched, cylindrical, septate, hyaline at the apex, pale brown at the base. Conidiogenous cells holoblastic, integrated, indeterminate, cylindrical, expanding towards the apices, pale brown, smooth, with 0–1 percurrent extensions. Conidia (51–)56–67(–76) × (9–)10–11(–11.5) μm, l/w = (5.2–)5.5–6.9(–8.1) (n = 50), variable in shape, curved, broadly fusiform to fusiform, cylindrical or clavate, dark brown, smooth-walled, 5–7-distoseptate, apical cell with a hyaline tip, truncate and black at the base.

CHINA. Beijing City: Songshan Mountain, on dead twigs of Quercus dentata, 15 June 2018, N. Jiang & C.M. Tian (holotype: BJFC -S1722; ex-type culture from ascospore: CFCC 52997). On PDA at 25 °C, colonies growing slowly and unevenly, reaching 70 mm diam. within 30 d, gradually becoming brownish dark grey in colour with scant cottony aerial mycelium, asexual morphs developed after 40 d.
