Index Fungorum number: IF833679, Facesoffungi number: FoF09618, FIGURE 6.

 

Asexual morph: Conidiophores 1–2 μm (x̅ = 1.8 μm, n=20) wide, macronematous, mononematous and synnematous, erect, straight, or slightly bent, simple, sub-cylindrical, hyaline to pale brown, smooth-walled, conidiogenesis terminal or intercalary, sympodial. Conidiogenesis cells 2–3.5 × 1.5–3 μm (x̅ = 3 × 1.8 μm, n = 20), monoblastic, discrete, sub-cylindrical to ampulliform. Conidia 5–7 × 2.2–3.1 μm (x̅ = 5.8 × 2.6 μm, n = 20), broadly ellipsoidal or rarely oval, hyaline to pale brown, 1-septate, constricted at the septum, verrucose, thick-walled, protuberant hilum. Sexual morph: Undetermined.

Culture characteristics: —  Colonies on PDA at 25 °C after 7 days become 4 cm diam., filamentous margined, hairy, and raised, brown to grayish brown at centre, flat, glabrous, dark brown at periphery, reverse dark brown, diffusible brownish pigment. Mycelium hyaline, aseptate, smooth at immature become septate, pale brown, 1–3 (x̅ = 2.5) μm diam. hyphae.

Known hosts and substrates: — soil (Hernández-Restrepo et al. 2020, this study).

Known distribution: —  Thailand (Hernández-Restrepo et al. 2020, this study)
