Index Fungorum number: IF 474783; Facesoffungi number: FoF 14272; Fig. X

Hyphae hyaline, aseptate, smooth-surfaced, becoming course-surfaced when mature. Asexual morph: Conidiophores 12–30 × 1–1.5 μm (x̅ = 22 × 1 μm, n = 20), mononematous, micronematous, erect, straight or slightly curved, smooth-walled, unbranched terminal or intercalary. Phialides 3–7 × 1–4 μm (x̅= 6 × 2.5 μm, n = 20), solitary on apices of conidiophores, ellipsoid to sub-cylindrical, bearing conidial chains at the apex. Conidia 2.5–5.5 × 1.5–4 μm (x̅= 3 × 2 μm, n = 20), globose or subglobose to ovoid, smooth-walled, hyaline, aseptate. Sexual morph: Undetermined.

Culture characteristics – Colonies on PDA become 30 mm diam. after 14 days at 25 ℃, appearing in white, becoming yellow to deep-yellow, cottony, slightly raised when mature, entire margined, reverse yellowish brown at the center and whitish yellow at the rind.
