Habitat:

Buried in the ground.


Host:

Lepidoptera larva.


Description:

Stromata solitary to several 25-45 × 2-3 mm, arising from head of infected Lepidoptera larva, sulphur-yellow to greenish-olive, the hosts’ bodies were covered with apple-green, paris-green mycelium. Perithecia semi-immersed, oblique in arrangement, ovoid, dark ostioles, 600-700 × 420-450 μm. Asci cylindrical, 300-420 × 3-6 μm with caps 5 × 5 μm thick. Ascospores hyaline, filiform, 200-300 × 2-3 μm.


Culture characteristics:

Colonies on PDA attaining a diam of 18–21 mm in 14 d, mycelium closely appressed and slightly convex in the middle of agar surface, flat, white at the margins turning greenish-olive and powdery while sporulating. Sporulation starts at 3 d after inoculation, reverse olive yellow in the middle of colony and white cream at the margin. Conidiophores arising from aerial mycelium, erect, smooth-walled, cylindrical. Phialides smooth-walled, cylindrical with semi-papillate apices, 7–10 × 1.5–2 μm. Conidia smooth-walled, greenish-olive, cylindrical with rounded apices or ellipsoidal, 5–9 × 2–2.5 μm.
