|46.||So here's the deal. Up until very recently, you could have called your mushroom "Cantharellus cibarius" if you had reached this point in the key, and you would have been in line with North American literature from field guides to websites (including this one) to scientific treatments. But thanks to recent research we are now in a transition. A few cibarius-like species have been described from our continent with contemporary (meaning: DNA-informed) concepts. Many more species are likely to ensue--and you can help mycology figure out what the species are. Please read the page for "Cantharellus cibarius," linked to the right, to find out how.|
