2 of 5: Thallus with regular dichotomous branching.

The undulated surface is not a common feature of the species. Thallus is flat, without a mid rib, and dichotomously branched. Cortical cells are angular, and cover one layer of large, medullary cells. The species is an annual species at the Norwegian coast and distributed north to the Trondheimsfjord. It but can be abundant in some years. It grows on rocks or on other algae in the subtidal and lower intertidal zone. In field it may be confused with the erect stage of Cutleria multifida, but can easily be separated from this species by a closer look at the apical tips.  Photo: © Vivian Husa Terms of use
