Type Information
Type locality: "fossil (Kreidemergel); drawing 2275 is from Oran, [Algeria] Africa."; (Jahn & al. 2008: 121) Lectotype: BHUPM; Ehrenberg’s drawing Nr. 2275 (detail in Fig. 1a) (Jahn & al. 2008: 121) Notes: BARCODE: EF164941 (Evans & Mann 2009: 72). "Epitypus (designated here to support the lectotype specified above): clone BLA4 (= SEL438B, isolated 5 June 2003 by Victor Chepurnov), preserved as a cleaned preparation of cell walls on slide E3640 (Royal Botanic Garden Edinburgh), which is mounted in Naphrax. A cox1 DNA barcode is available for clone BLA4, as GenBank accession EF164941 (Evans et al. 2007) and is also designated part of the epitype; an rbcL sequence for the same clone is available as GenBank EF143311. Two valves from E3640 are illustrated here (Fig. 2a, b), as are representative valves from natural populations of S. bacillum from Blackford Pond, Edinburgh, from which BLA4 was isolated (Fig. 2c–f). The ultrastructure, chloroplasts and mating of Blackford S. bacillum have been illustrated by Mann (1989, figs 2, 13, 14, 39 and 40). Locus epitypicus: epipelon in fine mud under 30–50 cm water at the SW end of Blackford Pond, Scotland (United Kingdom National Grid Reference NT253708), a small eutrophic freshwater lake." (Jahn et al. 2008: 122.
