Taxonomic remark According to Schopf et al., 1944, the type species S. papillata is described as measuring "1 inch across" and therefore most likely represents a sporangium, not individual spores. Another species, S. huronensis was described as "small globular papillate sporecases—probably of some Lepidodendroid plant", but in the opinion of Schopf et al., many examples probably represent the algal genus Tasmanites. Schof et al. go on to state: Dawson's Sporangites ... This name was first proposed in 1863 and has been used ambiguously and in different senses by many authors. It is here regarded as a nomen ambiguum and the name Tasmanites is adopted for the most frequently encountered forms that have been commonly assigned to Sporangites. [details]
