See text Leucosolenia is a genus of calcareous sponges belonging to the family Leucosoleniidae.

Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum.

They are most often observed in tide pools, clustered around the base of seaweeds or on rocks, and occur in a variety of colours, usually rather pale.

The colony consists of few simple vase-like, cylindrical individuals each terminating in an osculum and united at their bases by irregular horizontal tubes.

Lecosolenia is hermaphrodite, because both the gametes are formed in the body of same individual.
