I have a feeling that the americans would call this umbilicatum..
I’d call it rufescens (one of many forms), but here on MO, rufescens is deprecated in favor of repandum.
I found an interesting DNA study on Hydnum, published since that other obs was discussed:
It includes two american collections of umbilicatum, and the report shows that they are nested in the rufescens clade. They are also mentioning that a hole in the cap (umbilicate) occurs in several different lineages of rufescens, and is not a diagnostic character.
