Cristatella mucedo is found in North America, the British Isles, Europe and Asia.
It prefers still or slowly-moving waters but is otherwise broadly tolerant.
Cristatella mucedo colonies have been found in recently-formed gravel pits through to well-established sites (Okamura 1997) and from oligotrophic to eutrophic conditions.
Colonies are found attached to a range of natural and artificial substrata where they are protected from sedimentation – such as undersides or vertical faces.
