Colony encrusting, multiserial, unilaminar. Autozooids small, distinct, oval, slightly longer than broad, separated by deep furrows. Gymnocyst narrow. Cryptocyst extensively developed, depressed, flat and granular; mural rim salient, together with distal rim of opesia forming pear-shaped border around the cryptocyst and opesia; opesiules lacking. Opesia trifoliate, longer than wide, a pair of rounded indentations present in the proximal third. Oral spines present. Ovicell cribrate, ooecium represented by a pair of spine bases arranged parallel to the long axis of the zooid and bordering a depression on the proximal gymnocyst of the distal zooid. Avicularia and ancestrula not observed.
