Distinguishing features

Blunt-ended columns that may have a foliose base. Distinctive corallite pattern. Polyps often extended during the day giving the colony a furry appearance.

Description of colony by Benzoni et al (2010): "Colony growth form can be variable but most commonly it is digitiform. Digitations columnar to claviform [=club-shaped] up to 30 cm in height. Base of colonies can be encrusting or have free margins and become foliose. Digitations do not anastamose [link with each other] but, if claviform, can grow very close at top. Digitations circular to oval in section with rounded ends."

Similar taxa

  • Animalia: species: Psammocora digitata
    has tapering columns that are always oval in cross section, and can also be encrusting. The name P. digitata has been used extensively and erroneously for P. haimiana (Benzoni et al, 2010).
