Molleriella, introduced by Winter (1886) was placed in the class Discomycetes. Based on its morphology, Engler et al. (1897), and Hieronymus & Hennings (1901) placed this genus in Phymatophaeriaceae in Dothideomycetes. Later, Boedjin (1961) placed Molleriella in Saccardaiaceae. It was transferred to Myriangiaceae (Arnaud 1918) and to Elsinoaceae (Kirk et al. 2001, Lumbsch & Huhndorf 2007, 2010). Jayawardena et al. (2014) accepted this genus in Elsinoaceae based on morphological characters. It is a saprotrophic genus, characterized by locules with 4–10 asci inside each locule, asci with a minute pedicel, and irregularly arranged 6–8-septate, muriform, hyaline ascospores (see morphology in Jayawardena et al. 2014).
Type species: Molleriella mirabilis G. Winter.
Other accepted species: Species Fungorum – search Molleriella.
