General Description:

Called the scaly vase Chanterelle. This is a vase-shaped mushroom with a strongly depressed pileus that can range from 4-16 cm wide and up to 30 cm tall. However, 15 cm tall is the average. The upper surface of the pileus is a pale-orange to orange brown base covered in darker-orange to red-orange scales. However, with age, the scales can become more inconspicuous and the upper surface of the pileus can take on a more uniform color. The flesh is thick and fibrous. The underside of the pileus is a white to cream color, darkening with age, with strongly decurrent, blunt ridges that fork, superficially similar to the blunt ridges of true chanterelles. The stipe is hard to separate from the pileus but can be up to 10 cm long and up to 4 cm wide. Spore print is ochraceous to yellow-brown. Spore size can range from 11-20 × 6-10 micrometers. Spore shape can be referred to as elliptic with small warts and wrinkles. Can be found singly or in small clusters in mixed woods, seems to prefer hemlock. Thought to be ectomycorrhizal with conifers. A fairly common species that fruits from June-September.


Diagnostic Description:

Pileus that is very deeply depressed in the center. Dark/red-orange scales on upper surface can be very distinguishing if present. White to cream colored blunt, forked ridges that run from nearly top to bottom.


Distribution:

Having a fairly cosmopolitan distribution in the Northern Hemisphere, this species can be found throughout the northern and montane regions of North America. Most abundant in the moist parts of the Pacific Northwest. This species has also been observed throughout Asia including: Korea, China, Tibet, Nepal, India, and Pakistan.


Habitat:

Fairly common in North America, preferring northern and montane regions in moist habitats. Most common in mixed forests with large concentrations of conifers. Thought to form an ectomycorrhizal relationships with various conifers including: Pseudotsuga, Abies, Pinus and Tsuga heterophylla.


Look Alikes:

Can be confused with Gomphus kauffmanii. However, G. kauffmanii are a lot more rare and have numerous erect, dark brown scales on top of a tan to cinnamon-colored base. Also, the stem of G. kauffmanii stains pinkish-purple when bruised.

Can also be confused with the edible chanterelle, Cantharellus cibarius and related Cantharellus species. However, the upper surface of the pileus of C. cibarius is not nearly as deeply depressed in the center and could almost be considered planar. C. cibarius also has an incurved margin.

Uses:

Not recommended as an edible. Can be enjoyed by some but for most can cause gastrointestinal upset.
