Type species: Aldona stella-nigra Racib., Parasit. Alg. Pilze Java’s (Jakarta) 1: 19 (1900).

Notes: Aldona, typifided by Aldona stella-nigra was introduced by Raciborski (1900). The type was originally collected on living leaves of Pterocarpus indicus in Sumatra, western Indonesia. Aldona was initially placed in Hysteriaceae, then transferred to Phacidiaceae, and finally to Parmulariaceae (Saccardo 1904; von Höhnel 1917; Müller and Patil 1973; von Arx and Müller 1975). The genus was reported as pathogenic occurring on terrestrial habitats and bearing an asexual ceolomycetous morph (for morphology see Tian et al. 2015; Wijayawardene et al. 2018, 2020). Aldona is characterized by semi-immersed to erumpent, black, linear, radial or star-shaped, branching, coriaceous, shiny ascomata opening by longitudinal slits, black, shiny, globose or irregular spermatogonia growing on the spot, surrounded by ascomata and elongate-clavate, hyaline, transseptate ascospores with upper cells larger and wider, basal cells short and narrow (Tian et al. 2015).
