Reproductive morphology and <scp>DNA</scp> sequences of the brown alga Platysiphon verticillatus support the new combination Platysiphon glacialis
Platysiphon verticillatus , a brown alga endemic to the Arctic, was described based on vegetative specimens collected at Inglefield Bay, West Greenland. The species is distinctive in having a lanceolate blade‐like thallus terminated by a terete portion, both covered with hair‐like assimilatory filam...

Platysiphon verticillatus , a brown alga endemic to the Arctic, was described based on vegetative specimens collected at Inglefield Bay, West Greenland. The species is distinctive in having a lanceolate blade‐like thallus terminated by a terete portion, both covered with hair‐like assimilatory filaments. Punctaria glacialis was described from Eastern Greenland, and the species differs from other Punctaria species in lacking hairs and plurilocular zoidangia. Unilocular zoidangia were reported, but instead of zoids being released they formed cell walls in situ developing the appearance of plurilocular zoidangia. However, the fate of the zoids, as well as the walled cells was not traced, and the life history of the alga has remained unclear. By comparing DNA sequences ( cox 1, cox 3, and rDNA ITS 2) of specimens morphologically referable to Platysiphon verticillatus and Punctaria glacialis collected at Baffin Island, as well as re‐examining morphology and studying crude cultures, we concluded that they are the same taxonomic entity.
