Original diagnosis/description

Rosette-shaped sterile thallus, about 1 cm in diameter, apparently consisting of four main branches from the centre, which dichotomize twice, the ultimate segments attaining a width of about 1 mm. Margin of segments probably entire or slightly uneven, apex of lobes roundish or emarginate-bifurcate (corresponding to incomplete dichotomy). The segments are thinner marginally, and a kind of ribs or striae are present in the lamina, running obliquely to the margin of the segments. No ventral scales or rhizoids have been observed.
