Ophiocordyceps borealis

Ciri dan struktur

Parasitising Elateroidea larvae (Coleoptera) living in fallen wood. The larvae are cylindrical, 11 mm long and 1.1–1.3 mm thick, yellowish-brown; their body cavity stuffed with milky yellow mycelia and their intersegmental membranes covered with many milky yellow and flocculent funiculi. Stromata arising from any part of larval body, single or paired, unbranched. Stipe grey, slender and cylindrical, fibrous and flexible, curved more or less, 10–13 mm long and 0.25–0.6 mm thick, surface relatively smooth but with many longitudinal wrinkles, apex pointed. Fertile part irregularly attached on one side of the surface of distal part of stipe, which resembles a mass of insect eggs that are clustered together or separated into several lumps; substrate layer milky white, surface milky yellow accompanied by lavender and dotted with numerous black ostioles. Perithecia immersed, densely arranged, obliquely or at right angles to the surface of stipe, pyriform, neck unconspicuous, 220–290 × 120–150 µm and their tops obtuse; walls dark brown and 25–32 µm thick; ostioles slightly thickened and slightly protruding over the surface of fertile part. Asci cylindrical, 6–8 µm in diameter; caps hemispherical, 5–6 (x – = 5.5, n = 30) µm wide and 3.5–5 (x – = 4.2, n = 30) µm high. Ascospores filiform and elongate, multi-septate (far more than 3), not easy to break into part-spores; part-spores cylindrical, truncated at both ends, 10–15 (x – = 12.2, n = 30) × 2 μm. Asexual morph. Unknown. The new species is morphologically similar to O. purpureostromata (≡ C. purpureostromata), but their stipes and ascospores are distinct.
