Taxonomic remark From Steemans & Wellman, 2018: Tetraletes/Quadrisporites was for a long time considered a cryptospore by many workers. However, Bock et al. (2013), Le Hérissé (2002) and Wellman et al. (2015) demonstrated that it has escape structures and is almost certainly an algal resting cyst rather than a dispersed spore. Wellman et al., 2015 state: It is likely that Quadrisporites is a polyphyletic taxon (algal coenobia or cryptospores; see discussion in e.g., Strother (1991); Amenabar et al. (2006)). Tetraletes Cramer, 1966 is a junior synonym of Quadrisporites. [details]
