Abstract:

The incidence of Gracilaria bursa-pastoris, which is found mainly in Europe, in the northwest region of the Pacific Ocean was recently brought into question following the descriptions of G. parvispora and G. chouae from Hawaii and China, respectively. We examined the morphology of thalli previously identified as G. bursapastoris in Korea and Japan, and analyzed the plastid rbcL gene sequences of Korean and Japanese samples, and a G. parvispora sample from Hawaii. The morphological and sequence data both indicate identity between the taxon from Korea/Japan and G. parvispora from Hawaii, but significant differences exist between G. parvispora and G. bursa-pastoris from Europe. We propose that the thalli from Korea and Japan should be renamed G. parvispora. The rbcL tree grouped G. parvispora and G. damaecornis together, as a sister to the G. tikvahiae/G. isabellana/G. cuneifolia clade. This is the first recorded occurrence of G. parvispora outside Hawaii.
