Concentric hair lines alternating between both surfaces in unequal distance (2–3 mm apart on each surface), forming reddish-brown line at the upper end of a broad depressed line (0.1–0.15 mm wide) on inferior surface, but a red narrow line on superior surface. Thalli dioecious.

Antheridial sori in broken lines or patches near hair lines distally on inferior surface, without indusium.
