Barretomyces was named after Brazilian mycologist Prof. Dr. Robert W. Barreto acknowledges his contribution to mycology and plant pathology (Klaubauf et al. 2014). This monotypic genus consists of only its type species, i.e., Barretomyces calatheae, a popular hyphomycetous pathogen found in amphigenous spots on the leaves of Calathea longifolia in Brazil (Soares et al. 2011, Klaubauf et al. 2014). It was previously described as Pyriculariopsis due to having versicolored conidia bearing slightly paler basal cells and schizolytic secession (Ellis 1971). Later, this genus was created in accordance with multigene (ACT/ITS/RPB1) phylogeny and morphological uniqueness. The morphological difference between closely associated Pyricularia is visible through flat-tipped denticles with a central pore in Barretomyces (Klaubauf et al. 2014).
Type species: Barretomyces calatheae (D.J. Soares, F.B. Rocha & R.W. Barreto) Klaubauf, Lebrun & Crous
Other accepted species: This genus is monotypic.
