Ophiocordyceps khokpasiensis

Ciri dan struktur

Stroma solitary, simple, cylindrical, 16 cm long, 1 mm wide, brown (oac48-50), ca. 5.5 cm emerging above the leaf litter, ca. 10.5 cm buried in the soil. Asexual state (Hirsutella) produced ca. 1.5 cm at the terminal part of the stroma, light brown to grey. Perithecia pseudo-immersed, subglobose to broadly ellipsoidal, covering middle part of stroma, (200–)214–248.5(–250) × (120–)140–186(–200) µm. Asci 8-spored, filiform, (62.5–)86–115(–125) × 4–5 µm. Ascospores whole, filiform, (46–)51–74(–90) × 2–3 µm. Asexual state Hirsutella, phialides arising singly or laterally from the hyphae along the terminal part of the stroma, (8–)9–11(–12) × 3–4 µm. Conidia, hyaline, oval, 5–6.5(–7) × 2–3 µm. Colonies on PDA, attaining a diam. of 25.5 mm within 20 d at 25 °C, cream (oac900) to grey (oac893). Conidiogenous cells swollen towards the base, hyaline, smooth, tapering gradually towards the apex, which often forms a thin neck, monophialidic or polyphialidic, (15–)16.5–23(–28) × 3–4.5(–5) µm. Conidia arising from phialides at the apex of each neck, globose to oval, one-celled (4–)4.5–5.5(–6) × 2.5–4 µm, embedded in a mucous sheath. Colonies on PSA, attaining a diam. of 24 mm within 20 d at 25 °C, white to grey (oac843). Conidiogenous cells swollen towards the base, hyaline, smooth, tapering gradually towards the apex, which often forms a thin neck, monophialidic or polyphialidic, (14–)15.5–22.5(–28) × 3–4.5(–5) µm. Conidia arising from phialides at the apex of each neck, globose to oval, one-celled 4–5(–6) × (2–)2.5–3.5(–5) µm, embedded in a mucous sheath. Colonies on SDYA /4, attaining a diam. of 25 mm within 20 d at 25 °C, grey to brown (oac473).

Habitat dan peran ekologis

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.
