General Environment

Description
Thalli circular or semicircular, up to 7 cm in diameter, with entire margin, shallowly to deeply split into fan-shaped segments, attached by a stupose base with short stipe up to 3 mm long and 2.5 mm wide, yellowish brown to brown on inferior surface, white on superior surface, heavily calcified on both surfaces except for hair lines, resulting in striped appearance due to a repetitive pattern of calcified glabrous zone with an additional less calcified line at the center and naked hair lines on inferior surface, and substantially calcified zone on with a much more calcified line in equal interval on superior surface, two cells thick throughout; Vaughaniella stages common. Concentric hair lines alternating between both surfaces in equidistant (2–3 mm apart on each surface), forming a reddish-brown line at the upper end of a broad depressed line on inferior surface and a red, narrow line on superior surface. Thalli dioecious; both oogonial and tetrasporangial sori in continuous lines distally adjacent to hair lines on inferior surface, wholly embedded in a gelatinous layer, and covered with a persistent indusium; oogonia cylindrical and tetrasporangia obovate, 35.71 ± 3.96 µm wide, 85.5 ± 3.94 µm long, and 87.55 ± 2.37 µm wide, 147.4 ± 2.30 µm long, respectively; antheridial sori in broken lines or patches distally adjacent to hair lines on inferior surface, without indusium.
