Type species: Phaeoisaria bambusae Höhn., Sber. Akad. Wiss. Wien, Math. -naturw. Kl., Abt. 1 118: 329 (1909)

Notes: Phaeoisaria , typified by Ph. bambusae , can be easily recognized by its erect, brown, indeterminate synnemata with compact and parallel arrangement of conidiophores, sympodially extending polyblastic, denticulate conidiogenous cells and solitary, septate or aseptate, ellipsoidal, obovoid, fusiform-cylindrical or falcate conidia ( Cheng et al. 2014, Réblová et al. 2016 a, Luo et al. 2018). Currently, 23 epithets are listed in the genus, but only eight species are confirmed with molecular data ( Luo et al. 2019, Hyde et al. 2020a). Five species have been reported from freshwater habitats ( Luo et al. 2019). In this study, we collected a phaeoisaria-like taxon from submerged wood in a small river of Nakhon Phanom Province, Thailand. Phylogenetic analyses confirmed our new collection clustered in Phaeoisaria , and represents Phaeoisaria annesophieae .
