Helminthosporium meilingense

Ciri dan struktur

Description: Saprobic on decaying wood in terrestrial habitats. Anamorph hyphomycetous. Colonies on natural substrate effuse, scattered, hairy, brown to dark brown, velvety. Mycelium superficial and immersed in the substratum, composed of branched, septate, smooth, pale brown to brown, thick-walled hyphae. Conidiophores macronematous, mononematous, solitary or in groups of 2–4, simple, erect, straight or flexuous, cylindrical, smooth, 18–29-septate, blackish brown, paler towards the apex, with several cylindrical, enteroblastic percurrent extensions with well-defined small pores at the apex and laterally beneath the upper 1–5 septa, 544–712.5 × 12.5–17 μm (x ¯ = 622 × 15.2 μm, n = 8). Conidiogenous cells polytretic, integrated, terminal and intercalary, cylindrical, brown, smooth, with noncicatrized, distinct pores. Conidial secession schizolytic. Conidia acropleurogenous, solitary, dry, obclavate, rostrate, straight or curved, 6–13-distoseptate, pale brown, smooth, (20.7–)41.5–82.8 × 6.9–10.4 µm (x ¯ = 64 × 8 µm, n = 29), tapering to 1.7–3.5 µm near the apex, 3–7 μm wide at the base. Basal cell or apical portion sometimes with branches that developed a rostrate. Culture characteristics: Colony on PDA reaching 60–70 mm diam. after 4 weeks in an incubator under dark conditions at 25 °C, irregular circular, surface gray-brown with blackish brown in the center and gray mat of aerial hyphae at the margin; reverse rosy-brown with dark brown center and pale brown periphery.
