Cantharellus subpruinosus is a species of edible mushroom-forming fungus in the family Cantharellaceae. A European species, it was originally described from France in 2000, where it was found growing in moss in mixed deciduous and spruce woodland.
The cap of Cantharellus subpruinosus ranges from 20 to 70 mm in diameter. Initially convex, it flattens out with age and may become slightly depressed at the centre. The surface of the cap is smooth and has a silky to velvety texture, initially covered by a distinctive white powdery coating known as pruina, which makes young specimens appear almost white. As the fungus matures, the cap transitions to a vibrant orange hue, often becoming marked with ochre stains when bruised or handled. Its edge is distinctly wavy to lobed and retains remnants of the pruina even at maturity, gradually turning a rust-like shade.[1]
The underside features pronounced, decurrent folds (ridges that run down the stipe), which share the same general colouration as the cap and similarly stain yellow to orangey-ochre when touched. The stipe measures 20 to 70 mm tall and 10 to 30 mm thick, sometimes broadening slightly towards the top. Initially solid, the stipe gradually develops a hollow area towards its base, and its shape can vary from somewhat spindle-like to cylindrical-clavate (club-shaped). Typically, the stipe is slightly paler than or the same colour as the cap and likewise stains ochre upon handling.[1]
Internally, the flesh of the stem is whitish, contrasting with the orange flesh beneath the cap's outer layer. The fungus has a mild taste and emits a pleasant, fruity aroma reminiscent of apricots. Microscopically, the spores of C. subpruinosus are elliptical, occasionally kidney-shaped when viewed from the side, smooth, and transparent (hyaline), measuring roughly 7.5–8.5 by 4–5 μm. The basidia—the spore-producing cells—are elongated and club-shaped, typically bearing five to six spores each.[1]
