Helminthosporium guanshanense

Ciri dan struktur

Description: Saprobic on dead branches in terrestrial habitats. Anamorph hyphomycetous. Colonies on natural substrate effuse, scattered, hairy, brown to dark brown. 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, 10–34-septate, blackish brown, paler towards the apex, sometimes with cylindrical, enteroblastic percurrent extensions with well-defined small pores at the apex and laterally beneath the upper 1–5 septa, 282.5–977.5 × 15–20 μm (x ¯ = 700.3 × 16 μm, n = 10). Conidiogenous cells polytretic, integrated, terminal and intercalary, cylindrical, brown, smooth. Conidial secession schizolytic. Conidia acropleurogenous, solitary, dry, obclavate, rostrate, straight or curved, 5–14-distoseptate, pale brown, smooth, 55–107.5 × 10–15 µm (x ¯ = 85.8 × 13.7 μm, n = 21), tapering to 4.5–7.5 µm near the apex, 5–9 μm wide at the base. Culture characteristics: Colony on PDA reaching 55–65 mm diam. after 4 weeks in an incubator under dark conditions at 25 °C, irregular circular, surface reddish dark brown with gray white in the center and gray mat of aerial hyphae at the margin; reverse rosy-brown with black dots and pale brown periphery.
