Craterellus fallax

Craterellus fallax is a species of "black trumpets" that occurs in Eastern North America where it replaces the European taxon "Craterellus cornucopioides". "C. fallax" can also be separated by its yellow-orange spore print, where "C. cornucopioides" has a white spore print. It has often been considered a synonym of "C. cornucopioides", but according to Species Fungorum, it is a separate species. "C. fallax" is mycorrhizal, forming associations with "Tsuga" and "Quercus" species, among others. 
"C. fallax" is a choice edible fungus, although is not substantial.
