Color: Purple red

Thalli crustaceous, numerous branches arising from crust in advanced stage, sub-cylindrical or sub-compressed, 4-5 mm long, 1-2 mm diameter, sub-dichotomously branched or simple, usually anastomosing at the basal portion, apices of branches rounded or depressed.

In vertical section, hypothallium (medulla) marked coaxial, 100-190 µm thick, cells rectangular, 16-23 (-30) µm long, 6-8(-10) µm diameter, cells of perithallium (cortex) sub-rectangular, 10-16 µm long, 4-7 µm diameter, epithallium composed of single layer of cells, cells sub-rectangular to sub-triangular, 2-3 µm high, 4-5 µm diameter. Cell fusion often found between adjacent cell-rows of perithallium and hypothallium. Sporangial conceptacles multiporic, convex on surface of branches, 325-390 µm inside diameter, sporangia tetrasporic.
