Russula ochroleuca, commonly known as the Ochre Brittlegill, is a widespread fungus found in both deciduous and coniferous forests across North America, Europe and Asia. The cap, 5-10 cm in diameter, is typically ochre to yellow with a smooth, slightly sticky surface when moist, becoming matt and more brittle with age. It starts convex and flattens with a slight depression in the centre. The gills are white to pale cream, crowded, and brittle, a hallmark of the Russula genus. The stipe, or stem, is white, 3-7 cm long, and can become hollow as it matures. Russula ochroleuca forms ectomycorrhizal associations with trees, aiding in nutrient exchange and soil health. Although it is not considered toxic, its taste is bitter and acrid, making it generally inedible. The spore print is white, and spores are ornamented, ellipsoid, and amyloid.
