MycoBank number: MB 552086; Index Fungorum number: IF 552086; Facesoffungi number: FoF 02150, 2 species.

Foliicolous, associated with leaf spots or saprobic on dead twigs or branches. Sexual morph: Ascomata scattered, immersed to erumpent, black, globose to subglobose, ostiolate. Peridium composed of a few layers of brown to dark brown, thick-walled cells of textura angularis. Hamathecium comprising septate, cellular pseudoparaphyses. Asci 2–6-spored, bitunicate, fissitunicate, cylindrical, apically rounded. Ascospores 1–2-seriate, fusiform with broadly to narrowly rounded ends, yellowish brown to brown, 3-septate, smooth-walled. Asexual morph: Coelomycetous. Conidiomata pycnidial, solitary or gregarious, immersed or slightly erumpent, uniloculate or multi-loculate, globose to subglobose, ostiolate. Conidiomatal wall comprising a few layers, of lightly pigmented to hyaline cells of textura angularis. Hamathecium comprising cylindrical, smooth, flexuous, apex obtuse, hyaline, sparingly septate, paraphyses, intermingled among conidiogenous cells. Conidiophores reduced to conidiogenous cells or one supporting cell. Conidiogenous cell with supporting cell, hyaline, percurrently proliferating at the tip of the supporting cells. Conidia ellipsoid to subcylindrical, straight to slightly curved, golden brown to dark brown, 3(–4)-euseptate, apex obtuse, base truncate with a visible scar.

Type: Homortomyces Crous & M.J. Wingf.

Notes: Thambugala et al. (2017) introduced the monotypic family Homortomycetaceae to accommodate its type Homortomyces, as its phylogenetic placement is uncertain. Thambugala et al. (2017) placed Homortomycetaceae in Dothideomycetes, families incertae sedis.
