Rickenella fibula is a small, long-stiped, bright orange to yellowish fungus that occurs very widely on, or buried amongst, mosses. Microscopically, it is characterized by its conspicuous, large, long-necked cystidia on the gill edges and faces, stipe apex, and cap. Molecular analyses suggest that R. fibula is not closely related to most other gilled mushrooms, instead it falls within a heterogeneous group that includes mostly polypores and crust-fungi. R. swartzii (Fries) Kuyper is a similar, but less colorful, woodland species.
