NotesMycomicrothelia was introduced by Hawksworth (1985) to Arthopyreniaceae sensu lato and accepted 26 species. Most lichenized Dothidiomycetes are hyaline spored ascospores, while brown ascospores were placed in Mycomicrothelia whereas some species showed the basal position to Trypetheliaceae based on molecular studies (Nelsen et al. 2011a, Aptroot & Lücking 2016).
