Ophiocordyceps spicatus

Ciri dan struktur

Parasitising a Tenebrionoidea larva (Coleoptera) living in humid and decayed wood. The larva is cylindrical, 7.5 mm long and 1.0–1.1 mm thick, yellowish-brown. White mycelia stuff the body cavity, also partially cover the intersegmental membranes of the body surface. Stroma arising from the first quarter of the larval body, single, fleshy, 5 mm in length. Stipe yellow, cylindrical, 3.5 mm long and 0.35–0.4 mm thick, surface rough and pubescent. Fertile head spicate, unbranched, orange, 1.5 mm long and 0.5–0.7 mm thick, obviously differentiated from stipe; its surface rugged and consisting of many humps (outer portions of perithecia), tops of the humps obtuse and with opening ostioles, darker in colour. Perithecia partially immersed and obliquely or at right angles to the surface of stipe, broadly pyriform, 200–250 × 170–200 μm; walls 25–35 μm thick. Asci cylindrical, 5–9 μm thick, middle part wider than two terminal parts; caps hemispheric, 4.6–5.3 (x – = 4.9, n = 30) μm wide and 4.0–4.6 (x – = 4.3, n = 30) μm high. Ascospores filiform; part-spores cylindrical, truncated at both ends, 3.5–6.5 (x – = 4.7, n = 30) μm long and 1.7–2.0 μm thick. Asexual morph. Unknown. Ophiocordyceps spicatus is morphologically somewhat similar to O. formosana (Kobayasi and Shimizu 1981; Li et al. 2016), but it has a much smaller stroma (stipes 6–10 (or 19–37) mm long and 1.5–1.7 (or 2–4) mm wide in O. formosana), a spicate and rugged fertile head (surface entire and flattened, never spicate or rugged in O. formosana) and partially immersed perithecia (immersed in O. formosana). Nucleotide sequences of O. spicatus are most similar to those of O. formosana, but there is 5.2% bp difference in ITS, 2.0% bp difference in TEF1-α and 0.1% bp difference in SSU (LSU rDNA sequence unavailable for O. formosana).
