Saprobic on dead wood. Sexual morph: Ascomata hysterothecial, superficial or sunken in substrate, scattered to aggregated, oval to elongate, or globose to subglobose, black, carbonaceous, straight or curved, rarely branched, without subiculum. Ostiole central, slit-like. Peridium dark brown, thick, comprising a single stratum of dark brown cells of textura epidermoidea. Hamathecium comprising cylindrical to filiform, cellular or trabeculate pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, elongate cylindric-clavate, straight or slightly curved, short-pedicellate, apically rounded, with an ocular chamber. Ascospores 1-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 – Anteaglonium Mugambi & Huhndorf.
Notes – Anteagloniaceae was established by Hyde et al. (2013). Two genera, Anteaglonium and Flammeascoma are 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 in Anteagloniaceae, they are characteristically different from the genera of Hysteriaceae in having small hysteriothecial ascostromata and small ascospores. Molecular data also revealed that it forms a distinct clade within the Pleosporales. All the species of Anteagloniaceae were 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).
