    Thalli mostly growing in very dense bluish green clumps, with intricated fleshy stolons and a stiff-fleshy texture; erect branches very densely set, in such a way that they are contiguous, 1-2 (-3) cm high, unbranched, completely and very densely set by radially placed side branchlets of similar morphology over the whole length of the rachis which is not visible in these smaller specimens; plants of some collections are less dense and taller (3-5 cm high), the rachis sometimes branched once, with less densely placed side branchlets in the taller specimens, where the rachis becomes visible; side branchlets roughly trumpet-shaped, upwardly directed, shortly stalked, the inflated apical part being typically asymmetrically (tilted apically) compressed (turbinate with a convex tip) to almost complanate (peltate); light green.


Growing on horizontal substrate (coral rubble and on rocks) at shallow depth under low tide level.
