Parasitic in larva of Hepialus jianchuanensis, brown to dark brown, forming yellow to brownish stromata. Sexual morph: Thallus within host white, composed of intercalary hyphal bodies. Stromata mostly single, 140–145 × 2–4 mm, stipitate arising from head of the host. Stipe 12 cm long, 2 mm wide, clavate, with a fertile apex, becoming golden yellow to brownish yellow when mature. Fertile head 20–25 mm long, 2–4 mm diam., clavate, light yellow to yellow-brown, upper surface roughened, covered with white non compact mycelium. Ascomata 600–765 × 247–323 μm (x̄= 683 × 285 μm, n = 30), superficial, yellow to brown, flask-shaped, thick-walled, ostiole on the top. Peridium 63–42 mm (x̄ = 52 μm, n = 60) wide, three layers. Asci 186–228 × 8–12 μm (x̄ = 207 × 10 μm, n = 60), 8-spored, hyaline, narrow cylindrical, with a thickened apex. Apical cap 5–7 μm (x̄ = 6 μm, n = 60) diam. Ascospores 173–202 × 3–5 μm (x̄= 188 × 4 μm, n = 60) fasciculate, fusiform, smooth, as long as asci, hyaline, 10–18 septate, not breaking into secondly spores. Asexual morph: Undetermined.

Phylogram of Ophiocordyceps generated from Maximum likelihood analysis of SSU, rpb1 and tef1-α sequence data. Simplicillium lanosoniveum (J.F.H. Beyma) Zare & W. Gams is used as outgroup taxon. Maximum likelihood bootstrap values greater than 50 % and Bayesian posterior probabilities over 0.90 are indicated above or below the nodes. The new species are indicated in blue.
