Orange Mosscap
Rickenella fibula
Type: gilled mushroom

Physical Characteristics
The mushroom typically features a convex to flattened cap, often cream to yellowish-brown. The gills underneath are distinctive for their bright orange to yellowish coloration, which stands out against the lighter cap and stem. The stem is generally slender and off-white or yellowish. The size can vary, but caps are usually a few centimeters in diameter.
Habitat & Growing Conditions
Often found growing in clusters or individually on decaying hardwood logs and stumps, sometimes on conifer wood as well. It prefers moist, wooded environments.
Season & Fruiting Time
Commonly found from late spring through autumn, particularly after periods of rain when conditions are moist and favorable for fungal growth.
Similar Looking Species
Similar species include other small gilled mushrooms that grow on wood. Distinguishing features are primarily the vivid orange gills and the typically small size. Some species of Mycena or Marasmius might appear superficially similar but lack the striking orange gill color or have different growth habits. Careful observation of gill color, cap shape, and substrate is key for identification.
Ecological Role
This mushroom is a saprophytic fungus, meaning it obtains its nutrients by decomposing dead organic matter, primarily wood. It plays a crucial role in nutrient cycling in forest ecosystems by breaking down fallen logs and branches, returning vital nutrients to the soil.
Safety reminder
AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
