Rosellinia De Not., G. bot. ital. 1(1): 334 (1844)
Index Fungorum number: IF 4785; MycoBank number: MB 4785; Facesoffungi number: FoF 03064; 158 morphological species (Jayawardena et al. 2019), 27 species with sequence data.
Type species – Rosellinia aquila (Fr.) Ces. & De Not.
Notes – Rosellinia was introduced to accommodate uniascomatal species (De Notaris 1844). Petrini (2013) published a monograph accepting 142 species and several species were added (Ariyawansa et al. 2015, Su et al. 2016a, Tibpromma et al. 2017b, Fournier et al. 2017, Niranjan & Sarma 2018). We observed a herbarium specimen of Rosellinia bunodes (Fig. 268), the species occurred on dead wood and was described from Sri Lanka. It has long ascospores with thread-like ends and short germ slits. Rosellinia bunodes causes black root rot of fruit trees and vines, mainly in the tropics (Ten Hoopen & Krauss 2006, Castro et al. 2013, dos Santos et al. 2017).
