Unspecified note
Kusakina et al. (2006: 8) note that Codium from Malpeque Bay in PEI is probably an asexual variant of ssp. atlanticum. - (28 August 2006) - G.M. Guiry
Taxonomic note
Two supposedly introduced subspecies have been recognised in Britain and Ireland since Silva's (1955) study, viz, Codium fragile subsp. atlanticum (A.D. Cotton) P.C. Silva and C. fragile subsp. tomentosoides (van Goor) P.C. Silva. However, Maggs (in Brodie, Maggs & John 2007: 194) and Provan et al. (2008) have shown that the first is probably native, and the second, whilst introduced and invasive, is synonymous with C. fragile subsp. fragile. The degree of both genotypic variation reported (small) and phenotypic variation described (large) makes the described subspecies and varieties unsustainable and it would be better to recognise one variable species for all practical purposes. - (29 December 2007) - G.M. Guiry
