Scientific Description
Habit and structure. Thallus forming tufts and mats, light to dark brown with yellow to orange iridescence in shallow waters, composed of erect often arcuate axes, 5–8 cm high, arising from prostrate, stolon-like creeping axes 500–650 µm diam., these attached by small clumps of independent rhizoids formed from outermost cortical cells. Main axes cylindrical to compressed, 400–600 µm diam., bearing slender unilateral branchlets 200–400 µm diam., with numerous surface hairs distally.
Reproduction. Tetrasporangial sori in the distal ends of lateral branchlets; tetrasporangia borne on inner cortical cells, mostly tetrahedrally divided, 37–48 µm long and 22–28 µm wide. Other reproduction unknown.
Distribution. Known from Taiwan, Japan, Thailand, the Philippines, Indonesia, Hawai’i and north-western Australia.
Habitat. Epilithic in the intertidal.
