Fronds light green, composed of creeping, slender stolons 300-560 μm in diameter, bearing erect cylindrical siphons 1-3 cm high, and 5-7 times dichotomously branched finer siphons. Central axes 140-200 μm in diameter. Upper portions lax, forming distinct whorls that are crowded distally, lower portions 100-210 μm in diameter; individual upper whorl siphons, 30-40 μm in diameter, terminating in pointed and abruptly forked apices. Rhizoids branched and few.
