I have looked through the obs:es of acutoconica here. Though the persistens I have found can vary a lot, from pure yellow to more orange caps, white to yellow gills, and yellow to slightly orange stems, I have never seen them with such distinctly two-coloured caps as the ones you have here.
It’s just a matter of opinion if you give them ranks of species or varieties, but in my opinion, it’s always better with different species if you really are able to keep them apart. Here is a golden opportunity to do so, because acutoconica was originally described from USA, persistens from Europe, and no need to argue about which name to use..
persistens for the pure yellow one, originally described from Europe, and acutoconica for the American orange-tipped yellow one.
