; 8 species.
Saprobic on wood in terrestrial and freshwater habitats. Sexual morph: Ascomata perithecial, basally immersed to superficial, astromatic, globose to subglobose, lageniform to obpyriform, brown to black or yellowish, glabrous or slightly rugose, with a papilla or with upright neck. Peridium three-layered, comprising cells of textura angularis or textura prismatica or textura intricata, some with an orange, middle wall layer. Paraphyses numerous, septate. Asci 8-spored, unitunicate, cylindrical to clavate, short pedicellate, with a J-, distinct, refractive, apical ring. Ascospores uniseriate or overlapping uniseriate, oblong to ellipsoidal, fusoid to fusiform, straight or slightly curved, reddish-brown or greenish-brown to brown, darker at the median septum, 1-septate, with germ pores at one or both ends. Asexual morph: Undetermined (adapted from Réblová 2008 and Maharachchikumbura et al. 2016b).
Type genus: Jobellisia M.E. Barr
Notes: Jobellisiaceae was introduced by Réblová (2008) to accommodate a single genus Jobellisia based on LSU sequence data in the Sordariomycetes incertae sedis. In the phylogenetic analysis, Maharachchikumbura et al. (2015) introduced a new order Jobellisiales to accommodate this family, which was accepted by Maharachchikumbura et al. (2016b). With the use of molecular clock evidence, Jobellisiales fell in the ordinal time frame (146 MYA) (Hyde et al. 2017a). However, Hongsanan et al. (2017) stated that the placement of this order is unstable as sometimes it clustered with Pleurostomataceae.
