Rickenella fibula or Omphalina fibula, and commonly known as the orange moss navel is a species of fungus belonging to the genus Rickenella.

The fruit body is orange to yellow and occurs among moss, which is why it is sometimes called moss sentinel. The cap is quite small, with a diameter usually less than 1 centimetre (38 in). The stipe is relatively long, about 1.5–4.5 cm (581+34 in). It has little odor or taste, and is regarded as nonpoisonous. The spore print is white.
