  Thallus irregularly spreading, to 8 cm wide. Lobes plane to somewhat concave, sublinear, often overlapping at the margins, to 4 cm long, 5–15 mm wide, irregularly branched; margins undulate, somewhat upturned, at times deflexed at the apices, entire to phyllidiate-incised; phyllidia developing from thickened brown initials, restricted to the margins.
