Phidoloporidae Gabb & Horn, 1862

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. Some colonies are delicate and branching, not forming networks. Some genera are encrusting unilaminar; one forms nodular colonies. 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. Articulated oral spines may be present. A tubular pseudospiramen may develop on the proximal side of the peristome by coalescence of the marginal processes. Many genera have a denticulate distal margin to the orifice. Ovicells hyperstomial; prominent initially, becoming immersed in secondary calcification. Proximal margin of orifice may be elaborated into a projecting lip, or straight, or indented. Ovicell frontal may have entire calcification, or may be perforate with a pore, slit, or complex dentate fissure. Avicularia generally present, of varied types in different groups; mainly adventitious, with interzooidal avicularia in a few species.
