Saprobic on submerged wood or dead woody plant. Sexual morph: Undetermined. Sexual morph: Mycelium immersed, comprising septate, pale brown, smooth-walled hyphae. Conidiophores micronematous, macronematous, erect, simple or apically branched, sometimes proliferating percurrently in the apex, cylindrical, dark brown, septate, slightly constricted at septa, smooth-walled. Conidiogenous cells sympodial, terminal or intercalary, polyblastic, cylindrical, clavate to doliiform, hyaline towards the apex, brown at the base, with crowded conidiogenous loci inconspicuous to slightly prominent, refractive to somewhat obscure, more or less prominent denticles. Conidia acropleurogenous, oblong, obovoid, cylindrical, broadly fusiform to subpyriform, pale brown, rounded at apex, attenuate and narrowly truncate at base, brown, 0–3-septate, constricted at septa, smooth-walled, guttulate. conidial secession schizolytic. Synasexual morph: Conidiophores simple, erect, brown, smooth-walled. Conidiogenous cells terminal, discrete, phialidic, subglobose to lageniform, with a balloon- to funnel-shaped collarette, brown, often in clusters at the apex of the conidiophores. Conidia solitary, subglobose to obovate, unicellular, hyaline, guttulate, smooth-walled. (Dong et al. 2018, Wang et al. 2019, Hernández-Restrepo et al. 2020).
