Type species: Brefeldiella brasiliensis Speg., Boln Acad. nac. Cienc. Córdoba 11(4): 558 (1889).
Notes: The type collection of this genus was examined by Eriksson (1981), but specimens were considered immature (Hyde et al. 2013). Species of Brefeldiella are characterized by a superficial, irregularly arranged thin thallus, globose to subglobose flattened ostioles, thyriothecia, 8-spored, cylindric or clavate, fissitunicate asci with hyaline, oblong to ellipsoidal, 1-septate ascospores (Hongsanan et al. 2014a). Brefeldiella and Trichopeltella need molecular studies to investigate their separation (Hongsanan et al. 2014a).
