Abstract
Jolyna laminarioides gen. et sp. nov. (Scytosiphonales, Phaeophyceae) is described from Buzios, ''municipio'' of Cabo Frio, Brazil. The plants consist of one to several erect blades arising from a discoid holdfast. Anatomical features include a meristoderm, an outer and inner cortex, a transition region, a medulla that is composed of elongated cells (fiber-like cells), and a ground tissue made of a dense, irregular weft of interconnected filaments. The presence of a single chloroplast with a conspicious pyrenoid in each cell and of plurilocular organs on the macroscopic plant allows for placement in the Order Scytosiphonales; however, the sharply differentiated internal elements similar to those of the Laminariales lead us to propose a new genus and species.
