Type speciesKalmusia ebuli Niessl, Verh. nat. Ver. Brünn 10: 204 (1872).

Notes – Niessl (1872) introduced Kalmusia to accommodate Kalmusia ebuli as the type species (Ariyawansa et al. 2014d, Liu et al. 2015). Kalmusia species are characterized in having immersed to erumpent ascomata, filiform, delicate, septate pseudoparaphyses, bitunicate, clavate asci with narrowly ovoid to clavate, pale brown, 3-septate ascospores (Barr 1992a, Zhang et al. 2012b, Ariyawansa et al. 2014d, Liu et al. 2015). The asexual morph of this genus has coniothyrium-like, Cytoplea, Microsphaeropsis and Paraconiothyrium morphological characters (Zhang et al. 2012b, 2014b, Ariyawansa et al. 2014d). There are 27 Kalmusia epithets listed in Species Fungorum (2020).
