A slender, pale, club‑forming Cordyceps parasitic on Lepidoptera larvae and pupae. The fungus produces multiple thin, white to cream stromata emerging from the host, often from several points on the body. Stromata are smooth, cylindrical, delicate, and bear immersed perithecia visible as minute dots under magnification. This species is soft‑fleshed, unlike the tougher Ophiocordyceps sinclairii, and the host is always a moth or butterfly larva, never a cicada.

Stroma: 20–80 mm long White, cream, or pale yellowish Slender, cylindrical, sometimes slightly clavate Often multiple stromata from one host Perithecia immersed, giving a faintly roughened surface.
Host: larvae and pupae of moths and butterflies. Hosts may be: buried in soil attached to vegetation in leaf litter inside loose silk shelters
Base: Stromata arise from the mummified caterpillar or pupa, which may be partially buried or exposed.
Colour: Stroma: white to cream to pale yellow. Host: pale, mummified, often stiffened.
Size: Stromata: 20–80 mm long, 1–3 mm thick .Host larva: 15–30 mm long
Growth habit: Often several stromata emerging from a single host, giving a “tufted” appearance.
