Habitat:
In leaf litter.
Host:
Larva (Lepidoptera).
Description:
Stromata erect, multiple, cylindric to clavate, simple or branched, yellow-brown to orange, 9-48 × 2-4 mm, becoming purple in 3% KOH. Perithecia immersed, loose or compactly together, oblique in arrangement, ovoid with curved ostiole, 520-680 × 320-440 μm. Asci cylindrical, 8-spored, 210-400 × 2-5 μm, apical cap prominent, 2 × 2.5-3 μm. Ascospores filiform, with 15 septa but do not dissociate into part-spores, hyaline, 285-350 × 1 μm. The asexual morph was not seen in nature.
Culture characteristics:
Colonies on PDA slow-growing, floccose with phialides variable in shape and size, smooth-walled, consisting of a cylindrical or globose basal portion tapering into a long neck or may proliferate and form 2–3 lateral necks and started to produce globose to subglobose white conidia 1.5–2 × 2 μm after 3 wk in culture at 25 °C in the laboratory. The culture is whitish cream becoming light orange with age and did not turn green upon the production of conidia.
