Description

Saprobic on dead petiole of Licuala sp. Asexual morph: Hyphomycetous. Colonies sporodochia, broadly punctiform, gregarious, dark brown, raised. Mycelium partly immersed on natural substratum, partly surficial, comprising branched, pale brown to hyaline, smooth hyphae. Conidiophores reduced to conidiogenous cells. Conidiogenous cell 10–15 × 5–9 μm (x̅ = 12.6 × 6.8 μm, n = 15), monoblastic, holoblastic, integrated, determinate, cylindrical to obpyriform, pale brown to hyaline, smooth. Conidia 35–50 × 20–28 μm (x̅ = 43 × 24 μm, n = 25), acrogenous, solitary, dry, mostly irregular, subglobose to ellipsoidal, brown to dark brown, clathrate, muriform, 5–6-transversely septate, 2–4-longitudinally septate, slightly constricted at the septa, smooth and thin-walled, with a small, sub-rounded, depressions on the surface of each cell. Conidial secession schizolytic. Sexual morph: Not observed.

 

Culture conditions: Colonies on PDA after 2 weeks reaching 2–3 cm diam. at 25°C, circular, raised, surface velvety, aerial, sparser, grey; reverse dark brown to black.

Conioscypha verrucosa (MHZU 24-0486, new host record). a, b Colonies on substrate surface. c–h Conidia. i Germinating conidium. j, k The front of culture on PDA at 25℃ and the reverse of culture on PDA at 25℃. Scale bars: c–i = 10 µm.
