The type species (lectotype) of the genus Ankistrodesmus is Ankistrodesmus fusiformis Corda.
Status of Name
This name is currently regarded as a synonym of Messastrum gracile (Reinsch) T.S.Garcia.
Selenastrum gracile Reinsch
Syntype localities: "Altwässer an der Regnitz bei Erlangen" [Oxbows of river Regnitz near the city of Erlangen, Bavaria, Germany], "Gräben an der Regnitz bei Erlangen" [Ditches near river Regnitz near the city of Erlangen, Bavaria, Germany]; (Reinsch 1866: 65) Notes: "Lectotype (here designated): [icon] Reinsch, Abhandlungen der Naturhistorischen Gesellschaft zu Nürnberg 3(2): 65. Pl. IV: fig. IIIb. 1867. Krienitz & al. (1985: 81) preselected and reproduced figs III a, b as “Ikonotypus”. As mentioned above, Krienitz & al. (1985) did not effect a formal typification. Further material: No specimens located at M. The most relevant specimens are deposited at BM. BM 001045737 is labelled “Prep. Micr. Algolog. P. F. Reinsch 1874” and databased as “type”, but there is no indication that this material was in Reinsch’s hand when preparing the description of Selenastrum gracile. Because it is not possible to relate the Reinsch material to a concrete locality and to decide whether or not it is original material, we have chosen the image most similar to the current understanding of the species as the lectotype. Reference strains from Germany, Europe: CB 2009?35 (deposited as CCAC 9391B), 18S sequence: KT861784; KR 1981/231, 18S sequence: HM565930 (Krienitz & al. 2011). Reference specimen from Germany, Europe: B 40 0045158 (prepared from CB 2009?35). Reference strain from England: SAG 278.2, 18S sequence: Y16937. Reference specimen from Brazil, South America (as “epitype” in Garcia & al. (2016): SP 469319 (prepared from strain CCMA–UFSCar 622). Reference strain from Brazil, South America: CCMA–UFSCar 622, 18S sequence: KT833593; rbcL: KT355762, ITS2: KU180825." (Kusber & al. 2021: 3).
