Classification: Incertae sedis, Incertae sedis, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on tropical monocotyledons. Sexual morph: Stromata solitary or irregularly scattered, conspicuous, multi-loculate, superficial, with base slightly penetrating the epidermis at regular intervals, discoid to pulvinate, reddish brown to black, surface scurfy, flat or slightly convex. Ascomata deeply imbedded in stromatic columns, globose, with a long, periphysate, ostiolar neck. Peridium thick, composed of several reddish brown outer layer cells of textura globosa and textura epidermoidea, with pale brown to hyaline internal cells of textura angularis. 469 Paraphyses hypha-like, numerous, tapering towards the apex, not embedded in a gelatinous matrix. Asci 8-spored, unitunicate, broad cylindrical, short pedicellate, apically rounded or truncate, with a J-, discoid, refractive, apical ring. Ascospores bi-seriate, hyaline, 1-celled, ellipsoidal to cylindrical, smooth-walled. Asexual morph: Undetermined.

Notes: Catabotryaceae was validated by Barr (1990b) following Petrak’s (1954) invalid publication, which is monotypic and accommodates a single species Catabotrys deciduum. Barr (1990b) considered the centrum of Catabotrys as similar to that of taxa in Sordariales, and therefore proposed a monotypic family Catabotryaceae to accommodate and further placed it in Sordariales. Hyde & Cannon (1999) suggested Catabotryaceae could be included in Xylariales, as the centrum and stromatic features are more similar to Xylariaceae and Diatrypaceae. With phylogenetic analysis of the taxa in Sordariales, Catabotryaceae has been found transitory and placed in Sordariomycetidae family incertae sedis (Huhndorf et al. 2004b, Miller & Huhndorf 2005) and assigned in Amplistromatales (Maharachchikumbura et al. 2015). In a study of ranking fungi by using divergence estimates (Hyde et al. 2017a), Catabotryaceae has been shown to have a stem age of 165 MYA and therefore can be considered as an order. In this study the stem age was 171.92 MYA and therefore we place Catabotryaceae in a new order Catabotryales.

Type genus: Catabotrys Theiss. & Syd., Annls mycol. 13(3/4): 297 (1915).
