My reference is based on comments by Lodge. If you go to the H. acutoconica name page some more info is provided.

So clever!

I downloaded the paper mentioned below as Ref.. Is this the paper in which you based your comments?
This question appears to me because, going throughout it, I was unable to find anything that can support your comments related to my observations of H. acutoconica.

It doesn’t appear the information in the link you’ve provided is based on molecular data. The more recent work by Lodge et al. provides a clearer view of this species group.

I conclude that your sentence " H. acutoconica is a North American species " is not entirely correct. It could be described from North America, but that doesn’t mean that such species does not exist elsewhere. At the following link
one can see that H. acutoconica exist in europe and namely in Portugal. A list of synonyms and its sources is also provided.

If you click on the name H. acutoconica some more info has been provided in the description. H. acutoconica is a North American species. Hygrocybe persistens would be another option for European collections, it shows a 3.5% difference in DNA compared to H. acutoconica.

It can be!

But then you have to explain me why this is more like H. konradii than H. acutoconica. You cite a paper based on DNA analysis and for these specimens I didn’t make even microscopy. In my opinion the morphology points to H. acutoconica, as I understand it; Maybe it can not be distinguished on that basis from H. konradii.

Index fungorum is wrong.

See the work of Lodge et al. “Comparisons of ITS sequences by Dr. Karen Hughes and me confirms that Hygrocybe cuspidata is a synonym of Hygrocybe acutoconica, and that Hygrocybe konradii is a distinct species.”
I don’t see …

any advantage in changing the names of species to their synonyms, as is the case of H. acutoconica and H. konradii, according to Index Fungorum.
