Cystocarps 0.8-1.2 mm in diameter, usually 2-3 in corymbose papillae on margins and surfaces of the blade; carpospores subspherical, 13-17 µm in diameter. Spermatangial sori superficial, forming indefinite, irregularly anastomosing patches on the thallus surface or borne on thin, crisped triangular-shaped papillae with attenuated tips.
