Classification: Phaeococcomycetaceae, Lichenostigmatales, Arthoniomycetidae, Arthoniomycetes, Pezizomycotina, Ascomycota, Fungi

Based on the phylogenies of LSU and mtSSU analyses and morphological studies, Ertz et al. (2014) established Etayoa to accommodate the type species E. trypethelii (Phaeosporobolus trypethelii). Etayoa is characterized by dark brown to blackish stromata, subspherical to elongate, 8-spored asci, subspherical to shortly ellipsoid, hyaline ascospores, 1-septate, ellipsoid, with roundish apices; frequent conidiomata, absent conidiophores, pale to medium brown conidiogenous cells, shortly subcylindrical to almost ellipsoid, seceding with conidia, multicellular conidia, composed of conidiogenous cells and conidial cells; brown, subspherical, dry, single, verrucose, secession schizolytic, and conidial cells subspherical to ellipsoid (Ertz et al. 2014). No other species have been introduced to this genus, which remains monotypic. 

            Type species: Etayoa trypethelii (Flakus & Kukwa) Diederich & Ertz

Other accepted species: This genus is monotypic.
