The foliage indicates that it's one of the parsleys. The elongated fruits mean that it's not Torilis (hedge parsley) or Aethusa (fool's parsley), Sison (stone parsley) or Petroselinum (corn parsley). I'm not sure whether it's the common Anthriscus sylvestris (cow parsley) or Chaerophyllum temulum (chervil).
I can't agree more!
