NotesAposphaeria is characterized by pycnidial, unilocular conidiomata, short, cylindrical, branched conidiophores and hyaline, aseptate, cylindrical or ellipsoidal conidia (Tian et al. 2015). Some Aposphaeria species have been synonymized in other different genera, such as Chaetomastia, Massariosphaeria, Melanomma, Mytilinidion and Rhytidhysteron (Sivanesan 1984, Tanaka & Harada 2004, de Gruyter et al. 2013, Zhang et al. 2012b, Hyde et al. 2013, Tian et al. 2015). There is no molecular data for the type species, and Tian et al. (2015) suggested to retain Aposphaeria as a genus in Melanommataceae.
