Saprobic on the host plant in terestrial habitat or on decaying wood in freshwater habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown to black, stromatic, scattered or aggregated, superficial, unilocular, setose. Conidomatal setae brown to black, abundant, subulate to cylindrical, simple, septate, unbranched, smooth-walled, arising randomly throughout basal stroma. Basal stroma composed of thick-walled cells of textura angularis. Conidiophores lining the basal stroma in a dense layer, hyaline to pure brown, cylindrical, branched, thin- and smooth-walled. Conidiogenous cells hyaline, phialidic, subcylindrical to lageniform, determinate, smooth-walled, periclinal thickening towards apex. Conidia hyaline to pale brown, fusiform, with obtuse apex and truncate base, gently curved or straight, unicellular, bearing single, unbranched, flexuous, tubular appendage at each end.

Types species: Brunneodinemasporium brasiliense Crous & R.F. Castañeda, in Crous, Verkley, Christensen, Castañeda-Ruíz & Groenewald, Persoonia 28: 129 (2012)

Notes: Two taxa are currently recognizedin Brunneodinemasporium, B. brasiliense on decaying leaf in Brazil and B. jonesii on decaying wood in a freshwater stream in China (Crous et al. 2012b, Lu et al. 2016). Brunneodinemasporium jonesii has hyaline to pure brown conidia with mucilaginous balls connecting the conidia in short false chains, whereas B. brasiliense has hyaline to subhyaline conidia with bipolar appendages (Lu et al. 2016).

Distribution: China, Brazi (Crous et al. 2012b, Lu et al. 2016).
