Index Fungorum number: IF 822058; Facesoffungi number: FoF 03573

Holotype: HKAS 97444.

Etymology: ‘guangxi’ referring to collecting site.

 

Saprobic on submerged decaying wood. Sexual morph: Undetermined. Asexual morph: hyphomycetous, helicosporous. Colonies on the substratum superficial, effuse, gregarious, white. Mycelium composed of partly immersed, partly superficial, hyaline to pale brown, septate, sparsely branched hyphae, with masses of crowded, glistening conidia. Conidiophores 125–290 μm long, 4–6 μm wide, macronematous, mononematous, erect, flexuous, cylindrical, sparsely branched, septate, arising directly on substrate, pale brown, smooth-walled. Conidiogenous cells 10.5–16.5 μm long, 4–6 μm wide, holoblastic, mono- to polyblastic, integrated, terminal or intercalary, cylindrical, with denticles, pale brown, smooth-walled. Conidia 35–45 μm diam. and conidial filament 3.5–4.5 μm wide (x̄ = 38.5 μm diam., 3.8 μm wide, n = 50), 180–250 μm long, tightly coiled 2–2.75 times, becoming loosely coiled in water, rounded at the tip, multi-septate, guttulate, hyaline.
