Classification: Amphisphaeriales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Hemibiotrophic or saprobic on woody or herbaceous plants. Sexual morph: Pseudoclypeus comprising both host and fungal tissues, black. Ascomata immersed to erumpent, rarely superficial, solitary or aggregated, globose to subglobose, coriaceous, brown to black, ostiolate, papillate. Papilla short, narrow, internally lined with hyaline, filamentous periphyses. Peridium comprising dark brown to light brown, thick-walled cells of textura angularis, inwardly hyaline. Paraphyses numerous, hypha-like, septate, flexuose, embedded in a gelatinous matrix. Asci 8-spored, unitunicate, cylindrical to broadly cylindrical, pedicellate, with a wedge-shaped, J-, or J+, apical ring. Ascospores uniseriate to biseriate, hyaline to brown, ellipsoidal to fusiform, sometimes oval, straight or curved, unicellular or septate, wall smooth or ornamented or striate, sometimes with sheaths, appendages, rarely with germ slits or germ pores. Asexual morph: Undetermined.

Notes: Lindau (1897) resurrected Sphaeriales to accommodate Clypeosphaeriaceae which has been accommodated in Xylariales (Krug 1978, Barr 1990b, 1994, Eriksson & Hawksworth 1993, Eriksson & Winka 1997, Hawksworth et al. 1995, Smith et al. 2003, Douanla-Meli & Langer 2012, Hernandez-Restrepo et al. 2015, Maharachchikumbura et al. 2015, 2016b). Senanayake et al. (2015) excluded Clypeosphaeriaceae from Xylariales and transferred it to Amphisphaeriales. Jaklitsch et al. (2016b) did not accept Amphisphaeriales because it lacked phylogenetic support in their analysis. Furthermore, in their analysis, the generic type of Clypeosphaeria; C. mamillana clusters as a basal clade within Xylariaceae. Therefore, they discontinued Clypeosphaeriaceae and synonymised under Xylariaceae. However, in present study the family type; C. mamillana form a distinct clade apart from Xylariaceae as a sister taxon to the Induratiaceae. Therefore, here we maintain Clypeosphaeriaceae as a distinct family in Xylariales. However, most genera placed in this family lack molecular data and the arrangement is reliant on ascospores being apiosporous, asci having a J-, or J+, aprical ring and immersed ascomata.

Type genus: Clypeosphaeria Fuckel.
