Description:
Stroma solitary, simple, wiry to pliant or fibrous, arising from any point on the insect, dark grey to dark brown, 14 mm long, 1 mm wide on the underside of leaves of forest plants, unchanged in 3% KOH. Perithecia superficial, sparse, up to 20, covering middle part to apex of stroma, loosely scattered, vertically placed, ovoid, brown, 300-400 × 210-300 μm. Asci hyaline, cylindrical, 8-spores, 140-220 × 5-7.5 μm. Ascospores 135-215 × 2-3 μm, filiform, remaining whole after discharge, no septation.
Culture characteristics:
Colonies on PDA growing slowly, attaining a diam of 10–12 mm within 20 d at 20 °C. Colonies brownish grey to yellowish brown, velvety with depression on the colony, bearing conidiogenous cells and conidia of the Hirsutella asexual morph, colony reverse yellowish brown. Conidiogenous cells monophialidic or polyphialidic arising from hyphae laterally or terminally, hyaline, smooth-walled. Phialides 10–16 μm, basal portion globose 5–10 × 4––6 μm, phialide neck 2–8 × 0.5–1 μm, rough to warty. Conidia hyaline, 1-celled, smooth-walled, oval, 5–6 × 3–4 μm, without a mucous sheath.
