What species is this fast-moving spider?
Pawelek;

Unfortunately, I'm not very experienced at European spiders, but I suspect you're looking in the wrong place.  First of all, this appears to be an adult male spider (large ball-like structures at the ends of the pedipalps, in front of the 'face'), so the body pattern is probably going to be a bit different from the one you see on the females.  Male patterns are often an afterthought in identification references, unfortunately.

Secondly, this doesn't look much like a Pholcid to me - I'm getting more of a Linyphiid impression, from the shape of the abdomen, the visible patterns on cephalothorax and abdomen, and the filmy sheet it's hanging under.
I wish I could be of more help than this - but perhaps Ed Nieuwenhuys can help.  Here's a link to his site; if you look down toward the bottom, there's a contact link you could send him a photo and this question:
