Holotype:
CHINA, Yunnan Province, Jiangcheng County, Jiahe Town, Jiangxi village, 15 June 2022, H. Yu, holotype YHH 2206001, ex-type living culture YFCC 22069183.
Habitat:
Buried in soil.
Host:
On adult termites (Termitidae)
Description:
Stroma solitary, simple, cylindrical or clavate, glabrous, smooth, up to 11–16 cm long, 1–1.2 mm in diam, pale yellow, 9 cm emerging above leaf litter, 4 cm buried in the soil, fertileportion enlarging and generating toward the upper part of stromata, 30–35 × 1.2–1.4 mm, with perithecial apices. Perithecia pseudo-immersed, ovoid to pyriform, with short, exposed neck or rounded ostiole, 100–140 × 75–110 μm. Asci hyaline, filiform, 8-spored, 100–130 × 4–7 μm, ascus caps prominent, capitate, 3–4 μm high and 4–5 μm wide. Ascospores whole, hyaline, filiform, multiseptate, 100–130 × 1–2 μm.
Culture characteristics:
Colonies on PDA attaining a diam 5–6 cm in 30 d, mycelium abundant, cushioned, slightly convex, pale to ivory. Stromata emerging after 10 days, ivory to pale yellow, up to 25–40 × 1–2 mm, reverse pale yellow to dark purple. Asexual conidiogenous structures were not observed from the stroma. Hyphae hyaline, septate, smooth-walled. Conidiogenous cells arising from aerial mycelium on PDA, monophialidic or rarely polyphialidic, hyaline, smooth, swollen towards the base, flask-shaped, tapering gradually into a thin neck, 10–40 μm long, 2–6 μm wide at the base, 0.6–1.2 μm wide at the apex. Conidia solitary, smooth-walled, hyaline, ovate, 3–5 × 3–4 μm.
