Crous et al. (2017) established the genus Pseudodactylaria to accommodate Ps. xanthorrhoeae, the type species, and Ps. hyalotunicata. The type species was found on Xanthorrhoea sp. (Asphodelaceae) in Nullica State Forest, New South Wales, Australia (Crous et al. 2017). Currently, there are 10 accepted species of Pseudodactylaria listed in Species Fungorum (2024). Pseudodactylaria species have been reported on submerged decaying wood and twigs in freshwater habitats from China and Thailand (Tsui et al. 1997, Crous et al. 2017, Lin et al. 2018, Hyde et al. 2020, Lu et al. 2020, Bao et al. 2021, Boonmee et al. 2021), as well as in terrestrial habitats on Xanthorrhoea sp. (Asphodelaceae) from Australia (Crous et al. 2017). To date, no species of Pseudodactylaria have been reported from peat swamp forests. In this study, we found Ps. longidenticulata on submerged rachides of Eleiodoxa conferta from the peat swamp forest in Narathiwat, Thailand.

Type species: Pseudodactylaria xanthorrhoeae Crous, in Crous et al., Persoonia 39: 421 (2017)

Other accepted species: Species Fungorum – search Pseudodactylaria.
