staff vine or bittersweet

By the way, on the upper edge of your 3rd photo you can see a typical attribute of 'Euonymus verrucosus', the verrucous twig.

Oh...I'm sorry, the name is 'Euonymus verrucosus', I'm quite sure 'bout that. best wishes Roman

It's the one and only spindle in Austria which grows in relatively dry forests with warm summers (i.e. typical for pannonian climate within Austria). It's got black seeds. The quite whitish color of the fruit-hull on your pic might derive from a certain stage of fruit-development or other ecological circumstances. it occurs sometimes that plants do have untypical colors because of that so you shouldn't attach too much importance to this attribute in any case especially 'cos on one of your pictures there is a slightly reddish one.

I have a pic of one of this in Croatia. Tell me when you know the specific name: http://www.projectnoah.org/spottings/6409403

I think the genus is definitely Euonymus although I might not have the correct species. I have a similar spotting of an American Euonymus. http://www.projectnoah.org/spottings/7067481
