Habitat:
Buried in soil.
Host:
On Coleoptera.
Description:
Stromata solitary, cylindrical, gradually tapering toward the apex, moderate yellow to light yellow, up to 75 mm long. Stipes cylindrical, smooth, pale yellow, 1–1.5 mm wide. Rhizoids flexuous, 5 cm long buried under the ground, arising from head of Elateridae larva (Coleoptera). Fertile parts distinctly subterminal with asexual morph at apex. Ascomata subterminal, cylindrical, moderate yellow to light yellow, 10–20 mm long, 2–2.5 mm wide. Perithecia completely immersed, pyriform, 320–400 × 100–200 μm. Asci cylindrical, 90–200 × 4–6 μm with asci caps, 2–3 × 3–5 μm. Ascospores cylindrical, breaking into 32 small truncate part-spores, 3–7 × 1.5–2 μm. Asexual morph: Synnemata solitary, cylindrical, produced at upper region of the stipe, up to 60 mm long. Conidiogenous cells hirsutella-like, monophialidic or polyphialidic, cylindrical basal portion, 5–40 × 3–5 μm with a distinct, filiform, long neck up to 25 μm long. Conidia hyaline, smooth, globose, 2–4 μm.
Culture characteristics:
Colonies on PDA attaining a diam of 15–18 mm in 30 d, white, colonies reverse brownish orange. Conidiogenous cells polyphialidic, cylindrical to subcylindrical basal portion, 10–45 × 3–5 μm with a distinct, filiform, long neck up to 35 μm long. Conidia hyaline, smooth-walled, globose, 2–4 μm.
