Raja et al. (2012) established the family Natipusillaceae to accommodate the genus Natipusilla (Nat.), comprising four species (Nat. bellaspora, Nat. decorospora, Nat. limonensis, and Nat. naponensis) within Dothideomycetes. Subsequently, Hyde et al. (2013) introduced Natipusillales to accommodate Natipusillaceae based on the combined phylogenetic analyses of LSU and SSU sequence data. Members of Natipusillaceae have been reported as saprobes, occurring on submerged, decorticated, or corticated woody debris in freshwater streams and swamps (Ferrer et al. 2011, Raja et al. 2012, Hyde et al. 2013, Yang et al. 2023, Pem et al. 2024). The family is characterized by small ascomata that are globose to subglobose, hemispherical, umbonate, erumpent to superficial, and hyaline to light brown or black, occurring on submerged wood. The peridium wall is membranous, composed of pseudoparenchymatous cells arranged in a textura angularis pattern in surface view. Pseudoparaphyses are sparse and septate. Asci are globose, subglobose, obclavate, or clavate, eight-spored, with or without a short pedicel. Ascospores are fusiform to cylindrical, one to several septate, multi-guttulate or eguttulate, hyaline, brown to olivaceous brown, and may possess a gelatinous sheath and/or appendages. In this study, we describe a new genus, Narathiwatomyces (Nar.), to accommodate Nar. confertae, based on morpho-phylogenetic analyses. 

Type genus: Natipusilla A. Ferrer, A.N. Mill. & Shearer, Mycologia 103(2): 417 (2011).
