Hashimoto et al. (2018) established Lentistoma (Le.), as a new genus, accommodating Massarina bipolaris, which was renamed Le. bipolaris and designated as the type species. Lentistoma aquaticum was introduced by Dong et al. (2020) as the second species in this genus. Members of Lentistoma were found as saprobes on woody plants or submerged wood (Pinnoi et al. 2006, Pinruan et al. 2007, Hashimoto et al. 2018, Dong et al. 2020, Pem et al. 2024, Hyde et al. 2024). To date, one species of this genus (Le. bipolaris) has been reported from peat swamp forests (Pinnoi et al. 2006, Pinruan et al. 2007). In this study, we introduce Le. narathiwatense as a novel species found on the submerged rachis of Eleiodoxa conferta from the peat swamp forest in Narathiwat, Thailand. 

Type species: Lentistoma bipolare (K.D. Hyde) A. Hashim., K. Hiray. & Kaz. Tanaka, Stud. Mycol. 90: 169 (2018).
