The disc and the tentacles are orange or light brown. Most specimens have a delicate pattern of dark brown and white overlying this but it may be absent. Irregular streaks of opaque white may occur on the disc and tentacles. The tentacles are moderate in length and arranged in multiples of 6, in 5 cycles up to 96. The diameter of the base is up to 4 cm and the height is up to 5 cm. The base is broad and adherent. The major part of the column, directly above the base, is orange, red, brown or buff. The column above this is dark brown often purplish and with a white line encircling the upper-most limit.
