Taxonomic remark This is an extant genus, believed to be equivalent to the fossil Tasmanites which is an older name, although some workers consider that there is value in keeping the two names separate since the then-living organism from which the fossil cysts derived cannot be definitively studied. From ICNafp: Boalch and Guy-Ohlson (in Taxon 41: 529–531. 1992) united the two non-diatom algal genera Pachysphaera Ostenf. (1899) and Tasmanites E. J. Newton (1875) (Prasinophyta). Pachysphaera is based on a non-fossil type and Tasmanites on a fossil type. Under the Code in effect in 1992, Tasmanites had priority and was therefore adopted. Under the current Art. 11.8, which excepts only diatoms and not algae in general, Pachysphaera is correct for the combined genus. [details]
