Kuntze (1891) introduced Thozetella with T. nivea as the type species. Species of Thozetella are characterized by conidiophores that are grouped into short or long synnemata, terminated by phialidic conidiogenous cells, aseptate conidia, with unbranched setula at each end and sterile microawns (Paulus et al. 2004, Whitton et al. 2012, Hyde et al. 2020c). Twenty-seven morphological species of Thozetella are listed in Index Fungorum (2021), of which 16 have molecular data. We follow Hyde et al. (2020c) for the treatment and updated accounts of Thozetella. In this paper, we document Thozetella nivea from a freshwater habitat in Thailand. Freshwater Thozetella species include T. canadensis, T. coronata, T. cristata, T. cubensis, T. gigantea, T. nivea, T. pinicola, T. queenslandica, T. radicata, T. submersa, T. ypsiloidea (Sivichai et al. 2002, Pinruan et al. 2007, Barbosa et al. 2011, Barbosa et al. 2013, Pinruan et al. 2014, Monteiro et al. 2016, Fiuza et al. 2018, Calabon et al. 2022). 

Type species: Thozetia nivea Berk., J. Linn. Soc., Bot. 18: 388 (1881).

Other accepted species: Species Fungorum – search Thozetella.
