, and has a similar appearance. It is orange to yellow, meaty and funnel-shaped. On the underside of the smooth cap, it has gill-like ridges that run down onto its stipe, which tapers down seamlessly from the cap. The false gills often have a pinkish hue. It has a mild, sweet odor. It is solitary to gregarious in coniferous forests, fruiting from July to December.

The pacific golden chanterelle is the most important commercially-harvested Cantharellus species in the Pacific Northwest. This chanterelle has been designated Oregon's state mushroom, due to its economic value and abundance.

Description

Fruiting bodies
Basidiocarp
In fungi, a basidiocarp, basidiome or basidioma , is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures...

 colors varying depending on light levels and weather. In dry weather, the cap is medium orange yellow to light yellow brown, but wet weather may brighten the cap to brilliant to soft orange yellow. In low light conditions, caps may not develop the yellow pigmentation, resulting in salmon to rosy buff colors. The false gills
Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia or...

 in 1938. Despite this publication, the name C. cibarius continued to be used to refer to golden chanterelles in the Pacific Northwest. In 1997, Redhead et. al re-examined Corner's specimens, returned to the type locale, and collected new specimens, confirming the identity of C. formosus. DNA analysis has since confirmed the species-level rank of C. formosus.
