Notes – Caryospora was introduced by De Notaris (1855), and typified by Caryospora putaminum. Earlier, Caryospora was placed in Phaeophragmiae based on its terminal septa (Jeffers 1940), and later Hyde et al. (2013) placed it in Zopfiaceae. Based on the morphology and phylogenetic analyses, Caryospora was transferred to the newly-established family Caryosporaceae by Ariyawansa et al. (2015a). The species of this genus are collected from terrestrial and aquatic habitats (Abdel-Wahab et al. 2000, Raja & Shearer 2008, Ariyawansa et al. 2015a). Thirteen species have been reported in this genus (Barr 1979b, Hawksworth 1982, Raja & Shearer 2008, Hawksworth et al. 2010, Hu 2010), but only three have been sequenced (Ariyawansa et al. 2015a, Jayasiri et al. 2019).
