Parasitic on wasps (Hymenoptera), collected from the underside of leaves litter. Sexual morph: Host 11 mm long, 3–5 mm wide, black wasp without hyphae on the surface. Stromata 50–90 mm long, 0.5–1.5 mm diam, mostly single, stipitate, rarely double, arising from between the head and thorax of adult wasps, pale yellow to yellow. Stipe 25–27 mm long, 0.5–2 mm diam, clavate, with a fertile apex, becoming pale to yellow. Fertile head 3–3.2 mm wide, 1–1.2 mm diam, fusiform, yellow, upper surface roughened, lateral surface, ridged and furrowed. Ascomata 551–638 × 261–327 μm (x̄  = 594 × 294 µm, n = 30), immersed, oblique flask-shaped, thin-walled. Peridium 20–25 mm (x̄  = 23 µm, n = 60) wide. Asci 248–313 × 5–7 μm (x̄  = 480 × 6 µm, n = 60), 8-spored, hyaline, narrow cylindrical, with a thickened apex. Apical cap 5–12.5 × 8.5–10.4 μm (x̄  = 8.7 × 9.5 µm, n = 60) thick, with a small channel in the center. Ascospores easily breaking into part-spores, filiform. Secondary ascospores 3.1–3.9 × 1.6–2 μm (x̄  = 3.5 × 1.8 µm, n = 90) cylindrical, truncated at both ends, straight, hyaline, smooth. Asexual morph: undetermined. (Hyde et al. 2018)

Known hosts and distribution: on dead wasp (Chiang Mai, Thailand) (Hyde et al. 2018).
