Type Information
(Dixon & Price 1981: 137) Notes: Comments: the original treatment (C. Agardh, 1824: 140) cites three previously published binomials, one identification, and the manuscript source of the epithet. Despite widespread search we are unable to locate the type material of any of the previous binomials. Ceramium versicolor is a superfluous and illegitimate name, incapable of typification, which must be dismissed from consideration.
Origin of Species Name
Adjective B (Latin), changing colour, variously coloured (Stearn 1983).
General Environment
This is a marine species.

Nomenclatural note
Illegitimate: "[Ceramium versicolor C.Agardh] is illegitimate according to Art. 52.1 of ICN (Turland et al., 2018) because when C. Agardh (1824: 140) described his species, he listed among the synonyms Ceramium fruticulosum Roth, a species previously described by Roth (1800: 183)." (Cormaci & al. 2023: 322). - (21 November 2023) - M.D. Guiry
