DNA barcodes and morphometric data indicate that Codium fragile (Bryopsidales, Chlorophyta) may consist of two species

:The siphonous green alga Codium fragile currently has 10 accepted subspecies, among which is the problematic invasive subsp. fragile. The subspecies are defined on the basis of five polymorphic nucleotides in the plastid rps3–rpl16 spacer region, and this subdivision into subspecies has not been investigated in detail with other DNA markers. Here, we compiled a data set of the green algal DNA barcoding marker tufA that includes 110 C. fragile...
