Rickenella fibula or Omphalina fibula, and commonly known as the orange moss navel[1] is a species of fungus belonging to the genus Rickenella. It is orange to yellow and occurs among moss, which is why it is sometimes called moss sentinel.[2] The cap is quite small, with a diameter usually less than 1 centimetre (3⁄8 in).[3] The stipe is relatively long.[2] It has little odor or taste, and is regarded as nonpoisonous.[4]

According to molecular analysis, the species is more closely related to certain polypores and crust fungi than other gilled mushrooms.[2] A similar species is Rickenella swartzii.[2]
