Saprobic on the host plant in both terrestrial and freshwater habitats. The sexual morph is undetermined. The asexual morph is characterised by semi-immersed to erumpent pycnidial conidiomata, which are dark brown to black, separate to aggregated or confuent, unilocular or multilocular, apapillate, globose to subglobose, and ostiolate. The ostiole is short, circular and located in the center. The pycnidial wall is comprised of textura angularis, thick-walled and dark brown to hyaline cells. Conidiophores are reduced to conidiogenous cells. Conidiogenous cells are enteroblastic and phialidic, thick and smooth-walled, aseptate, discrete, lageniform to subcylindrical, and hyaline. Conidia are hyaline, smooth-walled, 0–1-septate, guttulate, oblong to cylindrical, and with rounded or obtuse ends (Li et al. 2016, Li et al. 2020).

Type species: Towyspora aestuari Wanas., E.B.G. Jones & K.D. Hyde, in Li et al., Fungal Diversity 78: 10.1007/s13225-016-0366-9, [35] (2016)

Notes: Towyspora was introduced by Li et al. (2016) based on T. aestuari as the type species, which was isolated from Phragmites communis. Towyspora was separated from Setoseptoria by its smaller conidia and forms a remote clade from Setoseptoria based on LSU, SSU, tef-1α and ITS sequence data (Li et al. 2016). Towyspora aestuari was also isolated from submerged decaying aquatic plants in Caohai Lake, Guizhou Province, China (Yang et al. 2023). Currently, there is one Towyspora species listed in Species Fungorum (September 2024). There are 17 sequence data available for Towyspora in GenBank (September 2024). The updated taxonomic treatment of this genus is Lentitheciaceae, in Pleosporales (Dothideomycetes) (Wijayawardene et al. 2022).
