Description. Massive-knobby, encrusting-lamellar or subdendroid, plocoid colony, with corallites that spiral around finger-like branches; circular or slightly oval calices scattered irregularly over the surface of colony; costosepta generally developed in 3 complete cycles.

Remarks. According to Beauvais (1982, vol. 2, p. 271–272), two syntypes exist of the species Actinacis reussi . He chose the specimen No. 24262 of the Oppenheim collection as the lectotype and gave its dimensions which considerably vary from the ones given by Oppenheim in his original description. According to Beauvais (1982), the dimensions of skeletal elements of the lectotype are: d=0.8–1.7 mm, c-c= 2–3 mm, and s=24.
