Fluminicola was introduced for a freshwater species F. bipolaris, and placed in Annulatascaceae based on morphology (Wong et al. 1999b). It is distinctive from other annulatascaceae-like genera in having immersed ascomata with a relatively long, upright neck erumpent through host substrate, and irregular bifurcate or cup-like bipolar appendages of ascospores, which are tiny and hyaline and difficult to be observed (Wong et al. 1999b, Zhang et al. 2017). Zhang et al. (2017) transferred Fluminicola to Papulosaceae based on sequence data from their three new species. The sequence data of the type species F. bipolaris is lacking and it has been missing for nearly 30 years since it was first collected from Philippines in 1994 (Wong et al. 1999b). Nevertheless, the molecular data of F. bipolaris is needed to confirm its generic status in Papulosaceae. In this study, we introduce a new species F. striata and synonymize F. thailandensis with F. saprophytica.
