Neokalmusia H. A. Ariy. & K. D. Hyde, Fungal Diversity 68: 92 (2014) Notes. Neokalmusia was introduced by Ariyawansa et al. (2014 b) to accommodate two species, N. brevispora and N. scabrispora (type species), which had been previously classified under Kalmusia (Tanaka et al. 2005; Zhang et al. 2009). Neokalmusia species have ascomata that are immersed to semi-immersed, globose to subglobose or oblong, with a clypeus-like structure; the asci are cylindric-clavate, with a long pedicel, and the ascospores are fusiform, yellowish-brown to reddish-brown and verrucose (Ariyawansa et al. 2014 b; Thambugala et al. 2017; Hongsanan et al. 2020). Currently, ten Neokalmusia species are listed in Species Fungorum (2025). Interestingly, all Neokalmusia species have a host preference on Poaceae hosts (Ariyawansa et al. 2014 b; Thambugala et al. 2017; Hongsanan et al. 2020; Hyde et al. 2020; Wanasinghe et al. 2022). In this study, we introduce a new host record of N. arundinis from another Poaceae host, Sporobolus alterniflorus.
