Due to the small size and substrate preferences of this species it is almost invariably damaged by collection and therefore problematic to recognise.
Lagenipora lepralioides is an encrusting bryozoan that forms small, thick white patches which are 2-3 mm in diameter. Colonies are rounded, lobed or star-shaped, with autozooids often arranged in a disorderly series. Autozooids are oval to hexagonal and very small: 0.3-0.4 mm long.
Lagenipora lepralioides is known from the English Channel, the Channel Islands and the western Mediterranean. It geographic distribution is incompletely known.
The species is able to colonise shell fragments and especially small pebbles, in offshore habitats.
