Craterellus Tubaeformis (Cantharellus Tubaeformis, Yellowfoot, Winter Mushrooms, Funnel Chanterelle)

Craterellus tubaeformis (Formerly: Cantharellus tubaeformis) is an edible fungus, also known as Yellowfoot, winter mushroom, or Funnel Chanterelle. It is mycorrhizal, forming symbiotic associations with plants, making it very challenging to cultivate. It is smaller than the golden chanterelle (Cantharellus cibarius) and has a dark brown cap with paler gills and a hollow yellow stem. C. tubaeformis tastes stronger but less fruity than the golden chanterelle. It has a very distinctive smoky, peppery taste when raw.

C. tubaeformis is a yellowish-brown and trumpet-shaped mushroom found in great numbers late in the mushroom season, thus earning the common name winter mushroom. The cap is convex and sometimes hollow down the middle. The gills are widely separated, and of lighter color than the cap. It grows on moss or rotten wood, is found mostly in conifer bogs. It is an excellent food mushroom, especially fried or in soups, and is easily dried for preservation.

Molecular phylogenetics has shown that C. tubaeformis deserves its reclassification from Cantharellus to Craterellus. Additionally, it appears that there are two distinct genetic populations that have traditionally been called tubaeformis: one in Europe and eastern North America, and another in western North America. If these two groups are defined as separate species, the "eastern" yellowfoot would retain the scientific epithet tubaeformis due to the origin of the type specimens in Sweden.

The western North American C. tubaeformis has been shown to make ectomycorrhizal relationships with western hemlock (Tsuga heterophylla) and Douglas-fir (Pseudotsuga menziesii). It is also most common in forests with a large amount of well-rotted coarse woody debris.
