Lu et al. (2018) introduced Neohelicosporium (Ne.), with Ne. parvisporum as the type species. Currently, there are 23 accepted species of Neohelicosporium listed in Species Fungorum (2024). Members of Neohelicosporium are reported as saprobes on decaying wood in freshwater habitats in China, India, Thailand, and the United States (Lu et al. 2018Pem et al. 2024). To date, no species of this genus have been reported from peat swamp forests. In this study, we describe Ne. arecacearum and Ne. narathiwatense as novel species found on palm materials (Arecaceae) and report Ne. fusisporum as a new host record on Eleiodoxa conferta from the peat swamp forest in Thailand. 

Type species: Neohelicosporium parvisporum Y.Z. Lu, J.C. Kang & K.D. Hyde.

Other accepted species: Species Fungorum – search Neohelicosporium.
