Some beards defy classification.Some are merely difficult to define because of the limitations of technology and time. For example, this Russian gentleman has some spectacular mutton chops.
Or are they?
Do those amazing wings growing on each side of his chin connect to his hairline with sideburns? If so, then these are mutton chops. If they also connect to the mustache then they are a subset of mutton chops called friendly mutton chops.
But what if they don't connect to his hair in front of his ears? What if the upper part of the cheeks where sideburns would go is clean shaven? It's difficult to tell from this photograph. If so, it might be classified as a hollywoodian except for the chin being clean shaven.
And what if the beard is not actually connected to the mustache. I can't even begin to determine how to classify that. "Freestyle" seems to be the convention in the modern taxonomy.
And the entirety of this confusion comes from the photograph. Were this gentleman standing before me, it would be easy to tell where there was hair and where there was not. It may be a little more difficult to classify but at least we would have a starting point
So, for simplicity, I shall declare that there is, in fact, hair in front of the ears and the mustache is connected to the beard, therefore: friendly mutton chops.
