Abstract

Peatswamp forest is a unique habitat that supports high biodiversity, particularly fungal diversity. The current study collected submerged and dead plant parts from Eleiodoxaconferta, Eugeissonatristis and Licualapaludosa from a peatswamp forest in Narathiwat Province, Thailand. Morphological features coupled with multigene phylogenetic analyses of ITS, LSU, rpb2 and tef1-α sequence data identified our isolates as new Distoseptispora species (viz. D.arecacearumsp. nov., D.eleiodoxaesp. nov. and D.narathiwatensissp. nov.). Morphological descriptions, illustrations and notes are provided.

Keywords: Sordariomycetes; asexual morph; molecular phylogeny; novel taxa; saprobic fungi; taxonomy.
