Taxonomy

The species was initially described as Cantharellus purpurascens by Lexemuel Ray Hesler in 1943, from material collected from forest around Indian Creek, North Carolina on 11 August 1940 by Hesler and A. J. Sharp.[3] It was given its current name in 1945 by Rolf Singer.[4]

Description

The fruit bodies are 4–10 centimetres (1.6–3.9 in) high with a cap that is 6–12 centimetres (2.4–4.7 in) across and is orange to salmon pink, turning wine-coloured when bruised or cut. The surface is smooth and the cap margins are inrolled in young mushrooms. The spore-bearing surface under the cap are gill-like ridges that are up to 3 millimetres (0.12 in) deep. These ridges fork 1–3 times along their length and are buff, turning dark purple when bruised or cut. The stipe is 0.8–2 centimetres (0.31–0.79 in) in diameter and 4–10 centimetres (1.6–3.9 in) high, cream when young and darkening to a clay colour when more mature.[1] It stains wine-coloured when bruised or cut.[5]

The dark purple bruising distinguishes it from edible chanterelles to which it has a superficial resemblance in shape.[1]

Ecology

In the United States it is found in the Great Smoky Mountains National Park in the Appalachian Mountains in North Carolina, where it grows in maple-hemlock forest.[5] It is mycorrhizal.[1] Mushrooms appear singly or in scattered groups of up to 30 in August and September.[5]

Its edibility is unknown.[1]
