Thallus medium to dark green, (1–)2–4(–6) cm high and (0.5–)1–2(–7) cm across, with a short stipe to 1 cm long broadening gradually or very rapidly into an ovate, reniform or irregularly elongate lamina, occasionally slightly lobed or lacerate, usually faintly zonate, thin (0.5–1 mm and several filaments thick), felt-like and spongy. Filaments slender, (12–)18–25 µm in diameter, thin walled, repeatedly subdichotomous and laxly interwoven, constricted adjacent to a subdichotomy, with branch ends forming the surface layer; chloroplasts ovoid, amyloplasts present.
Reproduction. From ovoid to pyriform, stalked zooidangia formed laterally on the medullary filaments.
