Morphology and multigene phylogeny reveal three new species of (Distoseptisporales, Distoseptisporaceae) on palms (Arecaceae) from peatswamp areas in southern Thailand.

Peatswamp forest is a unique habitat that supports high biodiversity, particularly fungal diversity. The current study collected submerged and dead plant parts from , and from a peatswamp forest in Narathiwat Province, Thailand. Morphological features coupled with multigene phylogenetic analyses of ITS, LSU, and sequence data identified our isolates as new species (viz. , and ). Morphological descriptions, illustrations and notes are provided.
