Description

Saprobic on dead inflorescence rachis of Livistona chinensis. Asexual morph: Hyphomycetous. Colonies on natural substrate sporodochia, scattered, dark brown or black. Mycelium partly immersed, partly superficial, composed of septate, hyaline hyphae. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 6–15 × 3–8 μm (x̅ = 9.3 × 4.9 μm, n = 10), monoblastic, integrated, terminal, globose or subcylindrical, hyaline, smooth-walled. Conidia 16–20 × 12–16 μm (x̅ = 18.6 × 14.2 μm, n = 25), acrogenous, globose, subglobose, ellipsoidal or obovoid, aseptate, thick-walled, verrucose, guttulate, brown, with a central basal pore. Sexual morph: Not observed.

 

Culture conditions: Colonies on PDA after 2 weeks reaching 8–9 cm diam., at 25°C, irregular, wrinkled, dense, white mycelium on the surface; in reverse cream.
