Short description Morphology

Thalli form greenish to cream amorphous clumps, attached by rhizoids at various points where segments get in contact with the substrate. Branches composed of moderately calcified flat segments with a distinct central rib, generally reniform to flabellate with the upper margin entire, sinuate to deeply lobed, 3 to 8 mm high, 4 to 10 mm wide, and 0.5 to 7 mm thick. Cortex consisting of 5 layers of utricles formed by repeated dichotomies from the medullary filaments; outermost utricles adhere slightly after decalcification, hexagonal in surface view, 23 by 40 to 50 μm in transverse section; secondary utricles about 17 μm wide. Central medullary filaments extend along the segments, terete and trichotomously branched, with evident constrictions at a short distance above the point of branching. Amorphous clumps up to 15 cm in diameter (Ref. 80758).
