tough to tell from pictures but those almost look more like gills than blunt ridges which would make it a false chanterelle. Are they pure white inside? Anyway I found some black trumpets the other day.
Just a guess off a pic, but my guess, which is usually fairly educated on such matters, is NO it's not what you think it is. Chant "caps" typically look like the bell end of a dented up French Horn. Chants also have non-typical or non-uniformed gills under the cap. Hard to ID from pics sometimes.
I'm positive those are not chanterelles in the first pic. But those are really beautiful chanterelles in the second. They have that nice creamy color. I found some last weekend on Mt. Nittany in Centre Co along with some sulfur shelf/chicken of the woods. Good eating.
