Description

Saprobic on dead segment of Livistona chinensis. Asexual morph: Hyphomycetous. Colonies on natural substrate superficial, effuse, white to yellowish, dense, shining, globose aggregated in a large mass. Mycelium mostly immersed, composed of hyaline hyphae, branched, septate, smooth-walled. Conidiophores 80–120 × 4.5–5.5 µm (x̅ = 97.2 × 4.9 µm, n = 20), macronematous, mononematous, single or in small groups, erect, straight or slightly flexuous, smooth-walled, dark brown at the base, becoming paler to subhyaline towards the apex, 3–8-septate, smooth, guttulate. Conidiogenous cells 15–25 × 3–5 (x̅ = 19.4 × 3.7 µm, n = 20), mono- or polyphialidic, with discrete, lateral phialides, integrated, terminal, with lateral openings formed by successive sympodial elongation, cylindrical to cylindrical-lageniform, with funnel-shaped collarettes, light brown at the base and becoming subhyaline to hyaline towards the apex, smooth-walled. Conidia 15–20 × 3–4.5 µm (x̅ = 18.1 × 3.7 µm, n = 20), falcate, asymmetrical, tapering toward both ends, aseptate, aggregated in large and slimy mass, smooth-walled, hyaline, with a straight or gently curved setula at both end, 7–8µm long. Sexual morph: Not observed.

 

Culture conditions: Colonies on PDA after 2 weeks reaching 4–5 cm diam., at 25 °C, filamentous, flat, with filiform edge, sparse, cotton-like, white aerial mycelium on surface, above white, yellowish in reverse.
