Corallina officinalis is a calcifying red alga, common in tide pools in the North Atlantic with occasional reports from the north-east Pacific. It is an important habitat-forming alga, providing shelter and substrata to many other organisms. To date there are only five published organellar genomes for Corallina , including C. chilensis and C. ferreyrae . This study reports the first four published plastid genomes for C. officinalis , along with three new mitogenomes from samples in the United Kingdom, Spain and Iceland. The plastid genome is 178 kbp and 99.9% of bases are identical for all samples. The mitogenomes are more variable than the plastid genomes, with lengths varying from 26.2 to 26.7 kbp and 99.0% base identity. Structure and length of both of the genomes are consistent with other published Corallina genomes. The most variable mitochondrial gene is sdh D (3.3% variability), while all plastid genes have <1% base variability, with the most variable being psb 30 (0.95% variability). The stability of the plastid genome means it is not useful for examining intra-specific variability within Corallina . We discuss whether the ratio of mitogenome and plastome sequences recovered in the readpool of NGS sequencing is indicative of relative copy number.
