Appearance
Adult fruiting bodies are trumpet- or vase-shaped with a scaly cap 5–15 cm in diameter and colored various shades of reddish- to yellowish-orange. The spore-bearing undersurface is irregularly folded or ridged rather than gilled and is pale buff or yellowish to whitish in color. The height of the fruiting body is around 8–20 cm , and there is no clear demarcation between cap and stalk. The spore print is brownish, the spores ellipsoid with dimensions of 12.4–16.8 x 5.8–7.3 μm.Distribution
The fungus appears to form ectomycorrhizal relationships with various conifers including Douglas-fir , fir , Pine and Western Hemlock . Fruiting bodies may be found in coniferous forests in North America, particularly the western states in late summer and autumn. They are most abundant in rainy parts of the Pacific Northwest. It also occurs through Asia, having been recorded from Korea, China, Tibet, Nepal, India, and Pakistan.Habitat

Consumption may result in nausea, vomiting and diarrhea. The onset may be delayed by up to 8–14 hours. A compound known as α-tetradecylcitric acid has been isolated from this species and may be the toxic agent.References:
