Diporula verrucosa is an erect bryozoan. Colonies arise from an encrusting base, developing into rigid, erect flat fan-shaped structures composed of irregular cylindrical branches. Colonies are light brownish in colour. Autozooids are broad, hexagonal to oval in shape. They are 0.6-0.7 by 0.5-0.6 mm.
Diporula verrucosa is a warm temperate species that occurs only rarely in the British Isles. It is found more commonly from the coasts of West Africa throughout the Mediterranean. In the UK the species has been recorded off the south Cornish coast where it is as the extreme northern limit of its range.
The species occurs in subtidal waters
