Ophiocordyceps asiatica

Ciri dan struktur

Stroma solitary, simple, filiform, up to 15 cm long, 1 mm wide, orange-brown (oac48-50), ca. 10 cm emerging above leaf litter, 5 cm buried in the soil. Asexual state (Hirsutella) produced at the terminal part of the stroma, ca. 2 cm long, light brown to grey. Perithecia superficial covering middle part of stroma, globose to subglobose, (240–)261.5–302(–320) × (180–)205–240.5(–260) µm. Asci 8-spored, filiform, (92.5–)104–143.5(–175) × 5–6.5 µm with cap, 2 × 2 µm. Ascospores whole, filiform, (80–)100–122.5(–132.5) × 1–2 µm, with septate. Asexual state Hirsutella, phialides arising singly or laterally from the hyphae along the terminal part of the stroma, (9–)9.5–13(–15) × (3–)3.5–4.8(–5) µm, conidia hyaline, fusiform, 4–5×2–3 µm. Colonies on PDA, attaining a diam. of 27 mm after 20 d at 25 °C, mycelium sparse to abundant, grey in the middle to pale brown. Conidiogenous cells developing directly on the aerial mycelium, swollen towards the base, hyaline, smooth, tapering gradually towards the apex, which often forms a thin warty neck (1 µm), monophialidic or rarely polyphialidic 15–18.5(–20) × 2–3 µm µm. Conidia aseptate, hyaline, smooth, arising from phialides at the apex of each neck, fusiform, (7–)7.6–9 × 2–3 µm, with a mucous sheath. Colonies on PSA, attaining a diam. of 25 mm after 20 d at 25 °C, Conidiogenous cells swollen towards the base, hyaline, smooth, tapering gradually towards the apex, which often forms a thin neck, monophialidic, (15–)17–21(–23) × 3–4 µm. Conidia aseptate, hyaline, smooth, arising from phialides at the apex of each neck, fusiform, (6–)6.5–8.5(–10) × 2–3 µm, with a mucous sheath.

Habitat dan peran ekologis

Thailand, only known from Khao Yai National Park. Parasitic on a pair of termites from a reproductive caste (Order Isoptera: Family Termitidae, Subfamily Macrotermitinae) and these specimens were buried in the soil. The fungus emerged from the segment between the prothorax and mesothorax of one of the termite pairs.
