Host:
Termite.
Description:
Stroma solitary, simple, cylindrical, 21.5 cm long, 0.5 mm wide, brown, ca 12 cm emerging above the leaf litter, ca 9 cm buried in the soil. Asexual morph (hymenostilbe-like) produced ca 5 cm at the terminal part of the stroma, light brown to brown. Perithecia superficial, subglobose, covering middle part of the stroma, 520-600 × 360-440 µm. Asci 8-spored, filiform, 160-165 × 14-17 µm. Ascospores whole, filiform, 107.5-147.5 × 6-7.5 µm, with 7-8 septa. Asexual morph Hymenostilbe-like. Conidiogenous cells forming a compact hymenium-like layer and had two to four denticles at their apices, cylindrical to clavate, 17-22 × 2-8 µm. Conidia hyaline, fusiform, 6-8 × 2-3 µm.
Culture characteristics:
Colonies on PDA attaining a diam of 26.5 mm within 20 d at 25 °C, white to grey. Conidiogenous cells arising from hyphae laterally or terminally, hyaline, tapering gradually or abruptly into a long slender neck.
