Voglmayr & Yule (2006) established Polyancora (Po.), as a new genus to accommodate Po. globosa, which was originally found on submerged leaves and twigs in tropical peat swamp forests in Peninsular Malaysia within Xylariales. Currently, only one species of this genus is listed in Index Fungorum (Hyde et al. 2024). Although there is one report of this species as an endophyte, the results are doubtful as it relied solely on the 18S rRNA sequence without morphological data. In the phylogenetic tree, the endophytic strain formed a separate clade from the type species of Po. globosa, raising questions on the identification of the species (Netala et al. 2016). Since the discovery of the type species in 2006, no further reports of this genus have been made from peat swamp habitats worldwide or from other habitats. In this study, we report Po. globosa on submerged rachides of Eleiodoxa conferta from the peat swamp forest in Narathiwat, Thailand, and provide rpb2 and tef-1α sequences of this genus for the first time.
