MycoBank number: MB 9053; Index Fungorum number: IF 9053; Facesoffungi number: FoF 06434; 1 morphological species (Wijayawardene et al. 2017a), 1 species with molecular.
Type species – Myxocyclus confluens Riess, Beitr. Mykol. 2: 63 (1852).
Notes – Sutton (1975a, 1977, 1980) transferred Hendersonia polycystis to Myxocyclus as M. polycystis and treated it as the synonym of M. confluens. Myxocyclus cenangioides introduced by Petrak (1927), was later excluded from the genus since the it is not congeneric with the type species (Sutton 1980). Tanaka et al. (2005c) showed Splanchnonema argus as the sexual morph of M. polycystis based on co-occurrence. Since S. argus is not the type species of Splanchnonema and it lacks sequence data to confirm whether it belong to Splanchnonema sensu stricto, Myxocyclus was not reduced under Splanchnonema. (see Wijayawardene et al. 2016a, 2017b; morphology, outline).
