Triphyllozoon Canu & Bassler, 1917

Type species: Retepora monilifera MacGillivray, 1860

Description: Colony generally erect, reticulate, forming a lacey network with zooids opening on one side of the branches, and with extrazooidal calcification on the basal side; colony attachment by thickened extrazooidal calcification at proximal portion. Zooid frontal with marginal pores only, surface smooth or pustulose. Zooid orifice with a sinuate or orbicular orifice; primary orifice often obscured by thickening frontal calcification. A tubular pseudospiramen may develop on the proximal side of the peristome by coalescence of the marginal processes. Ovicells hyperstomial; prominent. Articulated oral spines may be present. Proximal margin of ovicell straight. Ovicell frontal with complex trifoliate dentate fissure. Avicularia of varied types; mainly adventitious, with interzooidal avicularia, usually at the proximal margin of a fenestra.
