Notes – The genus was first established as a section of Leptosphaeria (Müller 1950). Later, Massariosphaeria was introduced by Crivelli (1983). Massariosphaeria is characterised by immersed ascomata, black, papillate ostioles, with black to grayish cells of peridium, abundant, hyaline, septate hamathecium, bitunicate, cylindric-clavate asci, fusiform, multi-septate ascospores, with relatively thick-walled, yellow to brown colour, some with transverse septum only, with the cell above the septum the largest, surrounded by a prominent mucilaginous sheath, sometimes forming red pigments, on the host, especially in culture (Tanaka & Harada 2004, Van 2005, Wang et al. 2007). Molecular data indicated that Massariosphaeria is polyphyletic (Wang et al. 2007). Since the sequence data of type species M. phaeospora is available and it clustered with strains of Cyclothyriella rubronotata (Wang et al. 2007, Hyde et al. 2013, Jaklitsch & Voglmayr 2016), Massariosphaeria was included in Cyclothyriellaceae (Jaklitsch & Voglmayr 2016, Wijayawardene et al. 2018).
