Tian et al. (2024) introduced Pseudosaprodesmium (P.), with P. cocois as the type species, found on dead leaves of Cocos nucifera in Thailand. Currently, there is only one species of Pseudosaprodesmium listed in the Index Fungorum (2024). To date, P. cocois has not been reported from peat swamp forests.  In this study, we describe P. narathiwatense as a novel species on the submerged rachis of Eleiodoxa conferta from the peat swamp forest in Narathiwat, Thailand.

Type species: Pseudosaprodesmium cocois X.G. Tian, K.D. Hyde & Tibpromma. 2024

Other accepted species: Species Fungorum – search Pseudosaprodesmium.
