Notes – Species of Eopyrenula are bark-inhabiting, facultatively lichenized with trentepohlioid photobiont. Eopyrenula has been moved from Dothideomycetes to Pezizomycotina by Lücking et al. (2017), but was maintained in Dacampiaceae by Doilom et al. (2018) who re- described the genus. A placement in the Pyrenulaceae (Eurotiomycetes) is also not excluded because of morphological similarities with Pyrenula from which it differs however by the absence of a well-developed pseudostromatic involucrellum, the absence of a thickened endospore and in having pycnidia with brown, septate macroconidia (Harris 1973). The six species of Eopyrenula were keyed out by Aptroot (2012) who treated the genus as part of Pyrenulaceae. It is provisionally maintained in Dacampiaceae here waiting for molecular data to clarify its phylogenetic position.
