Screening of diverse filamentous Ascomycota (Pezizomycotina) indicates that EHB are common among Pezizomycetes, Eurotiomycetes, Dothideomycetes, and Sordariomycetes that associate with plants (e.g., Hoffman and Arnold 2010, Hoffman et al 2013, Arendt et al 2016, Araldi-Brondolo et al 2017. They often form facultative associations, and many EHB can be removed by antibiotic treatments (Hoffman et al 2013, Arendt et al 2016.…”
