Symphoricarpos albus?

Euonymus sp.

I haven't found any matches from either genus. Maybe a close-up will help.

It is definitely Euonymus.

possibly this one

Or Euonymus bungeanus

Thanks, everybody, for your help. Euonymous kiautschovicus fruits are very close, but those plants are mostly listed as ranging to 10 feet tall. The one that has similar fruits in large shrubs (and the one that I'm leaning toward) is E. hamiltonianus in the "koi boy" cultivar. E. bungeanus fruits seem to be more angled than the ones shown in my photos.

Those last two are deciduous which this is not. Since it has a large habit like E. japonicus but fruits like E. kiautschovicus it is probably the latter, which is related to E. japonicus.

Thank you all. In light of Embothrium's comments, I'll go with kiautschovicus for the ID.

If I was on the scene I would next compare the found plant with labeled material in gardens and nurseries to see what matched it.

Thanks, Em. I was more interested in what it was, and whether it got there naturally. That plant was on a fence line along a highway. I did check the homes in the general area, and did not see additional examples. It was an unlikely spot for planting, so may have escaped. However, BONAP does not list kiautschovicus (in any cultivar form) in the wild. Since I'm not trying to find one for personal use, I'm satisfied with the ID - especially since it was roughly a 4 hour trip from home to the area where it was found.

"That plant was on a fence line along a highway." Quite possibly planted by a bird perched on the fence who had earlier, elsewhere eaten the fruit in a garden somewhere.

I've been reading about this plant, and there's currently disagreement about where it is placed. Kartesz (BONAP) treats this as Elaeodendron fortunei, while Weakley lists it as Euonymous fortunei. Both say that kiautschovicus is a synonym of fortunei, which is evergreen.
