Brunneodinemasporium Crous & R.F. Castañeda, in Crous, Verkley, Christensen, Castañeda-Ruíz & Groenewald, Persoonia 28: 128 (2012)
Index Fungorum, Facesoffungi number, MycoBank, GenBank Fig 1
Classification: Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetes, Ascomycota, Fungi
Saprobic on dead plant material, including leaves and stems of various grasses, bamboo, and decaying wood. The sexual morph is undetermined. The asexual morph is characterised by superficial cupulate conidiomata, which are stromatic, dark brown to black, solitary to gregarious, unilocular, globose. The cupulate setae are brown to black, simple, septate, subulate to cylindrical, thin- and smooth-walled, unbranched, abundant, and arising randomly throughout the basal stroma. The basal stroma is thick-walled and comprised of cells of textura angularis. Conidiophores are hyaline to brown, cylindrical, septate, unbranched, thin- and smooth-walled, and lining the basal stroma in a dense layer. Conidiogenous cells are phialidic, determinate, subcylindrical to lageniform, brown, smooth, and with periclinal thickening towards the apex. Conidia are hyaline to pale brown, thin and smooth-walled, eguttulate or guttulate, fusiform, gently curved or straight, obtuse to subobtusely rounded at the base, truncate at the apex. Conidia comprise with tubular appendage at each end, separated by a septum, or only with mucilaginous droplets at both ends (Crous et al. 2012, Lu et al. 2016, Li et al. 2020).
Type species: Brunneodinemasporium brasiliense Crous & R.F. Castañeda, in Crous, Verkley, Christensen, Castañeda-Ruíz & Groenewald, Persoonia 28: 129 (2012)
Notes: Brunneodinemasporium was introduced by Crous et al. (2012) based on B. brasiliense as the type species which was isolated from the decaying leaves of an unknown host. Subsequently, B. jonesii, was introduced from decaying wood in a freshwater stream (Lu et al. 2016) and B. sinense from dead leaves of Cyclobalanopsis glauca (Wu and Diao 2022) based on LSU and ITS sequence data and morphology. Currently, there are three species listed in Brunneodinemasporium in MycoBank (May 2024) and a total of 15 ITS and LSU are sequences available in GenBank (May 2024). The updated taxonomic treatment of this genus is Chaetosphaeriaceae, in Chaetosphaeriales (Sordariomycetes) (Wijayawardene et al. 2022, Hyde et al. 2024).
