The monotypic genus Towyspora was introduced by Li et al., (2016) to accommodate Towyspora aestuari based on phylogeny and morphology. The genus name is derived from the river Towy, Wales, in which the specimen was found. Towyspora is classified in Lentitheciaceae, Pleosporales, Dothideomycetes, Ascomycota (Li et al. 2016). Towyspora aestuari is saprobic on Phragmites communis (Poaceae); an aquatic shrub, and has semi-immersed to immersed, stromatic and pycnidial conidiomata. In the phylogenetic analysis based on ITS, SSU, LSU, and Tef sequence data, T. aestuari formed a separate clade from Setoseptoria with high bootstrap support. Towyspora is similar to Setoseptoria in having subcylindrical, hyaline conidiogenous cells and hyaline, smooth-walled, transversely euseptate, subcylindrical conidia with a single large central guttule per cell. However, Towyspora aestuari differs from Setoseptoria phragmitis, the type species of the genus Setoseptoria, which has smaller and aseptate conidia (Quaedvlieg et al. 2013). The sexual morph of the species is not determined.
