Seiridium cupressi

Ciri dan struktur

Sexual morph: Not observed. Asexual morph: Fruiting bodies scattered on the surface of Platycladus orientalis branches, carbon-black to jet-black; Conidiomata acervular, immersed to erumpent through bark tissue, black, subglobose, scattered, unilocular; wall brownish, 65–255 µm diam. Conidiophores long-cylindrical, hyaline, thin-walled, septate, occasionally branched, 16.3–51.4 × 1.0–2.6 µm; Conidiogenous cells hyaline, thin-walled, smooth, cylindrical, solitary, 5.9–17.5 × 1.1–4.2 µm (av. ± S.D. = 10.8 ± 3.2 × 2.0 ± 0.6). Conidia falcate to lunate, hyaline when immature, becoming pale brown to yellowish-brown at maturity, 5-septate, curved, with one hyaline apical appendage and one basal appendage, total conidial dimensions 19.4–29.8 × 6.2–11.9 µm (av. ± S.D. = 24.5 ± 0.4 × 9.6 ± 1.2), basal cell obconical, hyaline to pale brown, truncate, 2.5–7.1 µm long, the first cell from the basal cell upwards is 3.5–7.1 µm long, the second cell is 3.2–6.7 µm long, the third cell 3.1–6.0 µm long, the fourth cell 3.6–6.9 µm long, the apical cell conical, smooth, and hyaline, with a length of 1.6–5.7 µm. Appendages cylindrical, the apical appendages are mostly centric, 4.0–8.9 µm long, the basal appendages are mostly eccentric, 4.0–8.6 µm long. On PDA medium, colonies exhibited appressed growth with a sparse, felt-like texture and slow expansion rates, reaching approximately 30 mm in diameter after 7 days of incubation. Aerial mycelium was poorly developed and diffuse. After 2 weeks, a pale yellow pigmentation became visible on the colony reverse.
