Holotype:
THAILAND, Nakhon Phanom Province, Pla Pak District, 22 Jul. 2020, A. Khonsanit, S. Sommai, U. Pinruan, holotype BBH 49121, ex-type living culture BCC 93025.
Habitat:
Buried in soil.
Host:
On Termites.
Description:
Stroma solitary, simple, cylindrical, up to 6 cm long, 1–2 mm wide, brown, ca. 4–10 cm deep buried under the soil. The fungal stroma emerging from the segment between the prothorax and mesothorax of one of the termite pairs. Fertile part distinctly subterminal with asexual morph at the apex, ca. 14–15 mm long, 4–5 mm wide. Asexual morph (Hymenostilbe-like) produced ca. 3 cm at the terminal part of the stroma, light brown to grey. Phialides arising from the hyphae along the terminal part of the stroma, 5–17 × 4–6 μm. Conidia hyaline, fusiform, 8–14 × 2–4 μm. Sexual morph: Perithecia superficial, ovoid, covering middle part of stroma, 300–360 × 180–270 μm. Asci 8–spored, cylindrical, 140–227 × 7–15 μm with ascus caps, 3.5–5 × 6–8 μm. Ascospores whole, cylindrical with pointed ends, 35–80 × 5–6.5 μm, multi-septate, septa 5–19 μm long.
Culture characteristics:
Colonies on PDA attaining a diam of 5.5 mm in 20 d at 25 °C, dark greyish yellow to light olive brown, reverse moderate yellowish brown. Conidiogenous cells monophialidic, arising singly from hyphae laterally, hyaline, tapering into slender neck, 9–24 × 2–4 μm. Conidia hyaline, smooth, fusiform, arising from the apex of the neck, one celled, 6–18 × 2–4 μm.
