Note: The synonymy was proposed by Gomont (1892a: 353). When Kützing transferred Conferva chthonoplastes to Chthonoblastus, he changed the epithet to lyngbyei to avoid the formation of what he perceived to be a tautonym. The change is illegitimate, however, since the eschewed binomial does not fit the definition of a tautonym given in Art. 23.4. Microcoleus lyngbyei is also illegitimate since its authors were obligated to restore the epithet chthonoplastes. Drouet (1968: 109–110, 116), after examining the holotype of Conferva chthonoplastes (in C), assigned it to Schizothrix arenaria (Berkeley) Gomont.
