Type species – Saccothecium sepincola (Fr.) Fr.
Notes – Fries (1836) established Saccothecium and subsequently, several species were added to the genus based on morphology (Kirschstein 1938, 1939, Vasilyeva & Mel’nik 2006). Pande (2008) introduced several Saccothecium species, which had been classified under Pringsheimia or Metasphaeria, but most are invalid (Index Fungorum 2020). This genus is characterized in having immersed to erumpent, uniloculate ascomata and hyaline, 3 to many septate, muriform to phragmosporous ascospores.
