Habitat:
Buried in soil
Host:
Pupa of Lepidoptera
Description:
Stromata multiple, unbranched, 8–20 mm long and 0.5–2 mm broad, cream, cylindrical to enlarging apically, arising from the pupa in a cocoon (Lepidoptera). Fertile part orange yellow, 2–8 mm long, 2–3 mm broad. Perithecia superficial, narrowly ovoid, 500–580 × 120–180 μm. Asci cylindrical, 8-spored, up to 300 × 4–5 μm, with caps 2–3 μm thick. Ascospores hyaline, whole, bola-shaped, 3- or 5-septate, 180–300 × 0.5–1 μm, central part filiform, terminal part very narrowly fusiform, 20–50 × 1–1.5 μm. Asexual morph isaria-like. Synnemata multiple, unbranched, up to 12 mm long, 2 mm broad, moderate orange, cylindrical to clavate, arising from the pupa of Limacodidae (Lepidoptera) in a cocoon, white mass of conidia produced towards the apex of synnemata. Phialides verticillate, in whorls of two to five, 5–12 × 2–3 μm, with basal portion swollen to ellipsoidal, tapering into a distinct neck, 4–6 × 1 μm. Conidia in chains, ellipsoidal, white, 1.5–3 × 1–2 μm.
Culture characteristics:
Colonies on PDA moderately fast-growing, ca. 3 cm diam in 14 d at 25 °C, pale yellow pink, consisting of a basal felt and cottony, floccose overgrowth, reverse strong orange. Prostrate hyphae smooth, septate, hyaline, 2–3 μm diam. Conidial structures consisting of erect conidiophores usually arising from the aerial hyphae, verticillate with phialides in whorls of two to five. Phialides on PDA 5–12) × 1–3 μm, flask-shaped, tapering into long necks. Conidia on PDA in chains, oval with a pointed end, 1-celled, white, 1.5–3 × 2–3 μm.
