Classification: Bertiaceae  ,Coronophorales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood. Sexual morph: Subiculum inconspicuous or composed of brown to dark brown, branched, septate hyphae. Ascomata solitary or gregarious, superficial to erumpent, usually sitting on a subiculum, cupuliform, turbinate, globose to subglobose, carbonaceous to membranaceous, dark brown to black, tuberculate or smooth, collapsing, collapsing laterally or not collapsing, with ostioles or a papillate ostiole-like structure, without an external opening, periphysate. Peridium carbonaceous or membranaceous, outer layer composed of dark brown to brown cells of textura angularis, Munk pores present; inner layer composed of hyaline cells of textura prismatica. Paraphyses few, inflated, branched. Asci 8-spored, unitunicate, cylindrical to clavate, long pedicellate, apical ring indistinct or absent. Ascospores 2–3-seriate or irregularly arranged, hyaline to brown, ellipsoidal to fusiform, 0 to multi-septate, smooth-walled, mostly with guttules. Asexual morph: Undetermined (adapted from Mugambi & Huhndorf 2010, Maharachchikumbura et al. 2015, Hyde et al. 2020e).

Notes – Bertia is typified by B. moriformis and its species mostly have tuberculate ascomata and hyaline ascospores (De Notaris 1844, Mugambi & Huhndorf 2010). It is closely related to members of Nitschkiaceae based on multi-gene analyses (Huhndorf et al. 2004b, Mugambi & Huhndorf 2010, Maharachchikumbura et al. 2015, Hyde et al. 2020e).

Type species: Bertia moriformis (Tode) De Not., G. bot. ital. 1(1): 335 (1844).

Other accepted species: Species Fungorum – search Bertia.
