Saprobicon dead wood.Sexual morph:Ascomatahysterothecial, superficial or sunken in substrate, scattered to aggregated, oval to elongate, or globose to subglobose, black, carbonaceous, straight or curved, rarely branched, without subiculum.Ostiolecentral, slit-like.Peridiumdark brown, thick, comprising a single stratum of dark brown cells oftextura epidermoidea.Hamatheciumcomprising cylindrical to filiform, cellular or trabeculate pseudoparaphyses, embedded in a gelatinous matrix.Asci8-spored, bitunicate, fissitunicate, elongate cylindric-clavate, straight or slightly curved, short-pedicellate, apically rounded, with an ocular chamber.Ascospores1-seriate, very small, ellipsoidal, hyaline, 1-septate, constricted at septa, widest in the middle and tapering towards the narrow ends, straight, smooth-walled. Asexual morph: Coelomycetous or hyphomycetous.

Type –AnteagloniumMugambi & Huhndorf.

Notes –Anteagloniaceaewas established by Hyde et al. (2013). Two genera,AnteagloniumandFlammeascomaare accepted in this family (Mugambi & Huhndorf 2009b, Liu et al. 2015) containing eight and two species, respectively (Liu et al. 2015, Wijayawardene et al. 2017a, Jaklitsch et al. 2018b). Though hysterothecoid ascomata are found inAnteagloniaceae, they are characteristically different from the genera ofHysteriaceaein having small hysteriothecial ascostromata and small ascospores. Molecular data also revealed that it forms a distinct clade within the Pleosporales. All the species ofAnteagloniaceaewere supported by morphological and molecular data for their placement in this family (Mugambi & Huhndorf 2009b, Liu et al. 2015, Jayasiri et al. 2016, Jaklitsch et al. 2018b). The family also indicates a parallel evolution of hysterothecial ascomata in Dothideomycetes (Mugambi & Huhndorf 2009a, b).
