Rickenella fibula or Omphalina fibula, and commonly known as the orange moss navel [1] 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. [2] The cap is quite small, with a diameter usually less than 1 centimetre (3⁄8 in). [3] The stipe is relatively long, [2] about 1.5–4.5 cm (5⁄8–1+3⁄4 in). [4] It has little odor or taste, and is regarded as nonpoisonous. [5] The spore print is white. [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]
It may resemble its relative Loreleia marchantiae as well as Mycena acicula and Entoloma unicolor . The stems of Xeromphalina are darker. [4]
