Cyathophorum bulbosum is a creeping moss that forms erect and unbranched stems. The upper surface of each branch has two rows of large leaves and the lower surface has a third row of smaller leaves, which are not visible from above. Bulbous capsules are attached to the lower side of the stem on very short stems (setae) and are thus not readily visible.
Widespread in New Zealand in damp forest.
